Chapter 1: Life
Filament of DNA is information and messages are written using chemical where each letter is a chemical. Genetic code is a linear language and has an alphabet of only four letters: A, C, G and T. He also talked about the differences between DNA and RNA. RNA is more chemically active and unstable than DNA. Therefore, prehistoric ribo-organisms came up with DNA through an evolutionary trial.

Chapter 2: Species
Humans have 23 chromosomes and apes have 24 chromosomes. Human’s chromosome #2 is modified fusion of ape’s two medium size chromosome. The reason humans are so different than apes despite having 98% genetical similarity, is because of the adaptation to its environment. At one point in past, for some reason, maybe geological,

...be heavily punished. In fact, not only law yet every religion prohibit this kind of conduct, but still infanticide seems as just another crime in this globalization era. This paper aims to discuss about the law enforcement in reducing the number of infanticide in Malaysia. This paper analyses the provision of Section 318 of the Penal Code whether this Act is sufficient to punish the wrongdoer and any other solutions towards this cases. Besides, the role of Malaysia government in the enforcement of law and also how the authorities acts towards solving the cases of infanticide in Malaysia. Hence, the paper also analyses about the effects of law to the wrongdoers and given suggestions for further impacts, including Islamic viewpoints. 1. INTRODUCTION Infanticide can be defined as when any women by any willful act or omission causes the death of her newly-born child, but at the time of the act or omission she had not fully recovered from the effect of giving birth to such child, and by reason thereof the balance of her mind was then disturbed, she shall, notwithstanding that the circumstances were such that but for this section the offense would have amounted to murder, be guilty of the offence of infanticide (Section 309A, Penal Code Act 574). There are innocent babies that had been dumped every single week, according to the headquarters of Royal Malaysian Police (PDRM) by state...

EVOLUTION CONNECTION Life before and after Oxygen 91 102 103 Aerobic versus Anaerobic Lifestyles BIOLOGY AND SOCIETY Marathoners versus Sprinters Track-and-field athletes usually have a favorite event in which they excel. Some runners specialize in sprints of 100 or 200 meters. Others excel at longer races of 1,500, 5,000, or even 10,000 m. It is unusual to find a runner who competes equally well in both 100-m and 10,000-m races; most runners are more comfortable running races of particular lengths. It turns out that there is a biological basis for such preferences. The muscles that move our legs contain two main types of muscle fibers: slow-twitch and fast-twitch. Slow-twitch muscle fibers can contract many times over a longer period but don’t generate a lot of quick power for the body. They perform better in endurance exercises requiring slow, steady muscle activity, such as marathons. Fast-twitch muscle fibers can contract more quickly and powerfully than slow-twitch fibers but also...

Gene Regulation

...PYF12 3/21/05 8:04 PM Page 191 Chapter 12 Gene expression and regulation Bacterial genomes usually contain several thousand different genes. Some of the gene products are required by the cell under all growth conditions and are called housekeeping genes. These include the genes that encode such proteins as DNA polymerase, RNA polymerase, and DNA gyrase. Many other gene products are required under specific growth conditions. These include enzymes that synthesize amino acids, break down specific sugars, or respond to a specific environmental condition such as DNA damage. Housekeeping genes must be expressed at some level all of the time. Frequently, as the cell grows faster, more of the housekeeping gene products are needed. Even under very slow growth, some of each housekeeping gene product is made. The gene products required for specific growth conditions are not needed all of the time. These genes are frequently expressed at extremely low levels, or not expressed at all when they are not needed and yet made when they are needed. This chapter will examine gene regulation or how bacteria regulate the expression of their genes so that the genes that are being expressed meet the needs of the cell for a specific growth condition. Gene regulation can occur at three possible places in the production of an active gene product. First, the transcription of the gene can be regulated. This is known as transcriptional regulation. When the gene is transcribed and how much it is...

Epogen

...need of normal body and thus not carrying sufficient amount of oxygen to the body tissues. Erythrocytes are abundantly produced in bone marrow by the process of erythropoesis, initiated by the hormone erythropoietin, found in kidney. Patients with renal failure are unable to produce enough erythropoietin to stimulate the erythropoesis process, resulting in lower production of erythrocytes (RBCs). Epogen (Epoetin alfa) is a special drug to stimulate the production of RBCs. This drug is made by the DNA recombinant technology with certain limitations and controlled dosage to the patients. In patients with Chronic Kidney Disease (CKD), HIV infected patients being treated by zidovudine and cancer patients being treated with chemotherapy, Epogen dosages are 50-100 units/kg thrice a week, 100 units/kg thrice a week and 600-900 units/kg thrice a week keeping an eye on hemoglobin level. Epoetin alfa (Epogen) injection is limited to use in certain conditions such as, if hemoglobin level rises to 11 g/dL ten Epogen is prohibited to administer. There are certain side effects of consuming Epogen ranging from local, gastrointestinal to dermatological. Discussion Red Blood Cells (RBCs) are the essential part of human blood which carries oxygen to the body tissues. If there is lack of sufficient healthy RBCs in the body, the condition is called Anemia, ranging from mild to severe. Anemic patient mostly feel weak and tired. Anemia is of several types among which blood loss is the most...

...molecule The shape of a water molecule and its polarity make hydrogen bonding possible, A hydrogen bond is a weak attraction between a slightly positive hydrogen atom and a slightly negative atom. (They are partial charging) * Can occur between atoms of different molecule or within the same molecule * A single hydrogen bond is easily broken while multiple hydrogen bonds are collectively quite strong. * Help to maintain the proper structure and function of complex molecules such as proteins and DNA. Oxygen attracts the shared electric and is partially negative Hydrogens are partially positive. Properties of water * Water molecules cling together because of hydrogen bonding * This association gives water many of its unique chemical properties * Water has a high heat capacity * The presence of many hydrogen bonds allow water to absorb a large amount of thermal heat without a great change in temperature * The temperature of water rises and falls slowly * Allows organisms to maintain internal temperatures. * Water has a high heat of vaporization * Hydrogen bonds must be broken to evaporate water. * Bodies of organism cool when their heat is used to evaporate water. * Water is a good Solvent * Water is good solvent because of its polarity * Polar substances dissolve readily in water * Hydrophilic molecules dissolve in water (sugar) * Hydrophobic molecules do not dissolve in water...

Answers to Conceptual Sciences

...Answers to Conceptual Integrated Science End-of-Chapter Questions Chapter 1: About Science Answers to Chapter 1 Review Questions 1 The era of modern science in the 16th century was launched when Galileo Galilei revived the Copernican view of the heliocentric universe, using experiments to study nature’s behavior. 2 In Conceptual Integrated Science, we believe that focusing on math too early is a poor substitute forconcepts. 3 We mean that it must be capable of being proved wrong. 4 Nonscientific hypotheses may be perfectly reasonable; they are nonscientific only because they are not falsifiable—there is no test for possible wrongness. 5 Galileo showed the falseness of Aristotle’s claim with a single experiment—dropping heavy and lightobjects from the Leaning Tower of Pisa. 6 A scientific fact is something that competent observers can observe and agree to be true; a hypothesis is an explanation or answer that is capable of being proved wrong; a law is a hypothesis that has been tested over and over and not contradicted; a theory is a synthesis of facts and well-tested hypotheses. 7 In everyday speech, a theory is the same as a hypothesis—a statement that hasn’t been tested. 8 Theories grow stronger and more precise as they evolve to include new information. 9 The term supernatural literally means “above nature.” Science works within nature, not above it. 10 They rely on subjective personal experience and do not lead to testable hypotheses.

...Unit II: Genetics Brief Overview Reading: Chapters 3, 4, 9-12, 14 (Note: you have reviewed much of this already) The earth is teeming with living things. We can easily see some of the larger organisms—trees, grass, flowers, weeds, cats, fish, squirrels, dogs, insects, spiders, snails, mushrooms, lichens. Other organisms are everywhere, in the air, in water, soil and on our skin, but are too small to see with the naked eye—bacteria, viruses, protists (single celled eukaryotes such as amoebae), and tiny plants and animals. Life is remarkable in its complexity and diversity, and yet it all boils down to a very simple idea—the instructions for making all this life are written in nucleic acids, usually DNA. Most organisms have a set of DNA that contains the instructions for making that creature. This DNA contains four “letters” in which these instructions are written—A, T, G, and C. The only difference between the code for a dog and the code for a geranium is in the order of those letters in the code. If you took the DNA from a human and rearranged the letters in the right way, you could produce an oak tree—arrange them slightly differently and you would have a bumble bee—arrange them again and you would have the instructions for making a bacterium. Acting through more than two billion years, the process of evolution has taken one basic idea—a molecular code that uses four letters—and used it over and over, in millions of combinations to produce a dazzling array of life forms...

...Naturwissenschaften (2004) 91:255–276 DOI 10.1007/s00114-004-0515-y REVIEW Ulrich Kutschera · Karl J. Niklas The modern theory of biological evolution: an expanded synthesis Published online: 17 March 2004  Springer-Verlag 2004 Abstract In 1858, two naturalists, Charles Darwin and Alfred Russel Wallace, independently proposed natural selection as the basic mechanism responsible for the origin of new phenotypic variants and, ultimately, new species. A large body of evidence for this hypothesis was published in Darwin’s Origin of Species one year later, the appearance of which provoked other leading scientists like August Weismann to adopt and amplify Darwin’s perspective. Weismann’s neo-Darwinian theory of evolution was further elaborated, most notably in a series of books by Theodosius Dobzhansky, Ernst Mayr, Julian Huxley and others. In this article we first summarize the history of life on Earth and provide recent evidence demonstrating that Darwin’s dilemma (the apparent missing Precambrian record of life) has been resolved. Next, the historical development and structure of the “modern synthesis” is described within the context of the following topics: paleobiology and rates of evolution, mass extinctions and species selection, macroevolution and punctuated equilibrium, sexual reproduction and recombination, sexual selection and altruism, endosymbiosis and eukaryotic cell evolution, evolutionary developmental biology, phenotypic plasticity, epigenetic inheritance and...
