“In autosomal-dominant disorders, one mutated allele of the gene is enough to cause the disease” (para: Genetic Principles and Exceptions Thereof in Familial PD). There is some interest that DNA repair may play a factor in developing PD. According to a study published in 2012, researchers found 3 DNA repair gene variants that show association with increased risk for Parkinson’s disease (Gencer, M., Dasdemir, S., Cakmakoglu, B., Cetinkaya, Y., Varlibas, F., and Aydin, M., para: Conclusion). After

Biology Essays 1. The human population reached a new milestone on Oct 31, 2011. How does this impact evolution? Include climate change as one aspect of your response. (Think about Darwin's observations which led him to Natural Selection.) -The first sentence of this question refers to our human population reaching to about 7 billion people. To my knowledge the earth can hold that many people, but on the other hand, if our human population keeps growing, I think that then nature will select (according

Elizabeth Gossan Inherited genetic diseases - discuss Lynne Hampson 1,684 30/08/2014 Inherited Genetic Diseases – discuss. DNA is a large and complex molecule made up of a sugar phosphate backbone which consists of deoxyribose sugar bonded with phosphate groups. Then branching off the sugar phosphate backbone are complimentary nitrogenous base pairs which are Adenine, Thymine, Guanine and Cytosine. Transcription happens in the nucleus, where the double helix ‘unzips’ allowing mRNA to

mother, but is nearly independent of the age of the father. • Each time a cell divides, the genetic material becomes shorter. • The ends of the chromosomes, known as "telomeres", are important for the genetic stability of the cell and they act as a DNA clock that measures the age of the cell. • The cell stops dividing and dies when the telomeres become too short. • The discovery that the egg cell can extend the telomeres of a fertilizing sperm cell is important in the development of stem cell therapy

they are not safe, on the contrary others would insist that they are safe and risk-free. Although research may suggest that GMOs are safe, the scientific research that provides solid evidence that GMOs are risk-free, not only to humans and animals but also to the environment, is not sufficient. A wide variety of evidence connects GMOs with health problems, environmental damages, and the violation of farmer’s and consumer’s rights. I agree that GMOs are not safe because there are unknown side effects

cellular, organismal, population, community, or ecosystem BASIC STRUCTURE OF SCIENCE Biology has evolved as a field of science since it was first studied in ancient civilizations Science is a process that requires the testing of ideas using evidence gathered from the natural world. Science is iterative in nature and involves critical thinking, careful data collection, rigorous peer review, and the communication of results. Science also refers to the body of knowledge produced by scientific

Questions: (1 pt each response, 7 pts total) 3. What does your data indicate about the rate of cell division in cancerous tissue compared to the rate of cell division in normal tissue? What data did you use to answer this question? Answer: By comparing table 3 (normal cell tissue table) and table 4 (cancerous cell tissue table) I found that cancerous cell tissue has much faster rate of cell division. Specifically, I looked at the mitotic indexes on both tables and found that cancerous cell tissue
