If you were asked to get a genetic test panel performed, which diseases or health risks would you be interested in learning about and why?

Describe the biochemical composition, structure, and replication of DNA. Detail the role of specific RNA's in the process of protein transcription and translation.

Describe, in detail, one of the processes of cell survival. Describe how an abnormality in one of these cell functions causes cancer.

If it were me, I would be interested in learning about if I had the Alzheimer's gene or not. Since it does run in my family, there is a strong likelihood that I am carrying it. Other things I might want to know is the probability I could develop cancer. My mother died of it 10 years ago and although I am more genetically like my father, there is still a chance I am carrying the genes for it. I do not smoke, nor engage in any other physical contributors to cancer (which is not a guarantee I will not get it), so environmentally induced cancer is a small possibility. If I do get it, it will be genetic. Thanks mom!

DNA replicates in the nucleus of the cell. An enzyme breaks the hydrogen bonds between the two strands of the double helix. When the nitrogen bases are exposed, free-floating nucleotides in the nucleoplasm attach themselves to the exposed bases. Remember that A always bonds with T and C always bonds ...

Solution Summary

This solution explains how DNA replicates and how proteins are made. It also discusses how cells grow and divide, which when left unregulated, can be a cause for cancer.

Please Explain Each Problem

(Excerpted from attachment)

1: The term phenotype refers to the _________ of an individual.
2: With respect to sickle cell anemia, I write that the genotype of an individual is AS. Which of the following statements are true?
3: If, in the Hershey Chase experiment, only 35S entered the bacterial cell in significant amounts, the conclusions would have:
4: During the replication of DNA:
6: Mutations at more than one gene can cause the same phenotype. For example several enzymes are used to make methionine. Defects in any of them produce an organism that cannot synthesize its own methionine. Oculocutanious albinism can also be caused by defects in several different genes. Of the following statements which are true?
7: In a double-stranded DNA molecule, the percentage of thymine is 28%. What percentage of cytosine is present?
8: Many types of research about genes' roles in cancer employ mice. Why use mice when we wish to cure cancer in humans?
10: If you were going to look for a gene that was often transcribed, where would you look and why?
