they originated from. By performing DNA analysis of these fluids or stains, a genetic marker profile can be obtained that is essentially specific to that individual. At a crime scene, many types of biological evidences may be present. Each type of biological evidence has a unique importance and its own probative value. Ordinarily, biological evidence are photographed or collected from crime scene and sent to the laboratory for a DNA investigation. The DNA specific to each individual is an effective

Study Guide: Biochemistry A. Hydrophilic vs Hydrophobic. Since biological chemistry occurs largely in an aqueous environment, the interaction of a biological molecule with water is very important. That interaction is influenced by two primary causes: size and polarity (charge). The smaller a molecule is, the more likely it is to be willing to associate with water (dissolve). Also, the more polar and/or charged a molecule is, the more likely it is to be willing to associate with water.

Nucleus is surrounded by a nuclear envelope - Nucleus is separated from cytoplasm by double membrane - It functions as an intermediary when DNA replication is taking place during cell cycle. - It contains hereditary materials DNA and RNA - It directs activities of the cell such as growth, metabolism and reproduction. - It create different type of RNA from DNA in the process called Transcription - It is control centre of the cell Nucleolus Inside the Nucleus (Centre) - It is spherical in shape

and conduct the usage of carbon dioxide and water. This process is called photosynthesis. After the process of photosynthesis, there comes the production of sugar. Animals are able to use sugars delivered by the plants in their individual energy storage called the mitochondria. The mitochondria produces a form of energy currency and it creates ATP (adenosine triphosphate). The ATP is a highly energetic molecule that supplies the vitality we need to get our bodies to function properly. The energy’s

of hybrid seed purity is done conventionally by grow out test, which is based on the assessment of morphological and floral traits in plants grown to maturity, which locks up the capital while awaiting the results for GOT. GOT could be replaced with DNA based assays. The present investigation was undertaken with an objective to identify distinguishable microsatellite markers to establish fingerprinting of rice (Oryza sativa L.) hybrids, assessing variation within parental lines and testing the genetic

IncorrectQuestion 1 0 / 1 pts Which of these is an example of homeostasis? Hummingbirds prefer to feed on nectar from red flowers. Homeostasis is the maintenance of the body's internal state within a relatively narrow range. When the dog's body temperature becomes too high, the animal feels hot. He opens his mouth, lets his tongue loll out, and pants until he feels comfortable again. A shark can detect even minute quantities of blood in the water. Venomous coral snakes and harmless

Missing Genetic Link in Human Evolution” by Emily Singer is an article relating to the human genome and evolutionary discoveries. Evan Eichler, a geneticist at the University of Washington, revealed a set core duplicons which is defined as “stretches of DNA that appear over and over on a specific chromosome”. These core duplicons is like a site on the chromosomes that duplicates genes or even delete certain genes. Eichler believes that this has been one of the fastest evolving human genes and shows high
