decides whether or not to replicate its DNA. At the checkpoint the cell is checked for DNA. Cells with no damaged DNA (normal cells) continue to S phase, in S phase cells with damaged DNA (cancerous cells) that cannot be repaired die. G2 is when cell is about to divide. the M is

than any other dinosaur. It killed its brother and escaped and started to terrorize and kill visitors in the park. All this happened because they were playing God. They wanted to play God and make a creature of their own and so they rewrote the DNA genetically. Now imagine you having a baby, it's perfectly normal and healthy right now, but you decide to go and genetically modify your baby anyway. Everything goes well for a while and then you find out that Joseph Flores your baby has a deformity

Polydactyly, sometimes referred to as a congenital anomaly is a conditions where someone has more than five fingers or toes on each hand or foot. The disease is present at birth, and the digits can usually be removed soon after. Polydactyly affects about one in every seven-hundred babies, and surgery to remove them is fairly simple. They can vary in severity and can range from small skin tags to fully formed extra fingers. Polydactyly is the addition of another finger or toe, however it is very

Cells in apoptosis show typical morphological characteristics, such as cell volume decrease, folds in the cytoplasmic membrane, condensation and fragmentation of DNA, maintenance of the integrity of organelles, with the shape of apoptotic bodies and posteriorly phagocytosis b/*y macrophages. This process is mainly regulated by cell signaling routes, and pro- and anti-apoptotic proteins that control the process involved

Prokaryote comes from the Greek word meaning pre nucleus. The DNA is not enclosed within a membrane has a singular circularly arranged chromosome. Prokaryotes DNA does not contain histones but does have other proteins. They divide by binary fission, this is when the DNA is copied and the cell divides into two cells. The prokaryote does not contain a membrane-enclosed organelle. The prokaryote cell wall contains the complex

With the growing of scientific and technological advances today, it should come as no surprise that designer babies have now become a possibility. The term designer baby refers to how certain attributes of a baby can now be modified to our perceived advantage to create a perfect child. This, of course, is absurd, as these modifications will create ethical issues relating to fairness, harmful consequences, and morality human rights and justice, the dignity of an individual, issues of morality, religion

sequence of Nitrogenous bases in DNA DNA is the principle molecule responsible for carrying genetic information within almost all living organisms for their development. They also provide some of the apparatus by which the instructions are carried out. This excludes viruses, as they use RNA, to carry their genetic information. (Image 1: DNA molecule, nucleotide, base pairing. Reference: http://www.britannica.com/EBchecked/topic/422006/DNA-sequencing ) Structurally, the DNA molecule consists of two

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

Genetic disorders are an unfortunate but real part of human life. There are thousands of genetic disorders in the world, some more common than others. Genetic disorders may vary in regards to manifestations in people from age, gender, health, population, and many more factors. For example, there are X-linked disorders which are carried by women and present mostly in males, such as color blindness. There are also disorders which are much more prevalent in men such as color blindness, and disease much

complex and larger(80S) than ribosomes in the prokaryotic cell(70S). The ribosomes makes protein in both and can be found floating within the cytoplasm and RER (only in eukaryotic cells). Both cells have DNA as their genetic material, but the DNA of eukaryotes is held within its nucleus.Eukaryotic DNA is linear and is associated with histones (proteins). Hence the nucleus is absent in
