Our understanding of the molecular biology of cancer formation has been greatly enhanced by studying oncogenic viruses. Answer the following questions regarding oncogenic retroviruses? What is an oncogene? How does if differ from a proto-oncogene? Why are retroviruses prone to accumulating oncogenes? Explain how a gain of function mutation in the Ras protein caused by a retrovirus might lead to cancer formation
Why does a single mutation in a proto-oncogene, turning it into an oncogene potentially lead to a cancerous phenotype, while it takes two mutations in tumor suppressor genes to lead to a cancerous phenotype?
What is the difference between a proto-oncogene and an oncogene? a. oncogenes cause benign tumors (polyps), proto-oncogenes cause malignant tumors b. oncogenes transform cells to hyperproliferation, proto-oncogenes have a normal cellular role c. oncogenes have undergone post-translational modification, proto-oncogenes have not d. oncogenes have undergone intron splicing, proto-oncogenes have not
How many copies of each type of core histone would it take to wrap the entire human genome into nucleosomes? How has evolution solved the problem of producing such a large number of proteins in a relatively short period of time?
What role Proto-oncogenes play ?
Since all cells contain the same number of chromosomes and the overall same/similar genome how would the genome in a nerve cell work differently than the genome of a muscle cell? In other words what epigenetic processes cause these differences between cell types at the molecular level

What is the function of a proto-oncogene?
What is the difference between a prophage and a Lysogen?
If you were to design an experiment to get p53 back into cancer cells, how would you go about that work? How would you direct p53 into the nucleus of cancer cells without directing it to the nucleus of healthy cells? As an overabundance of p53 in healthy cells would cause problems. Could someone in depth answer these questions for me and explain them cellularly.
One important biological effect of a large dose of ionizing radiation is to halt cell division. What might be the effects of such a mutation if the cell is not irradiated?
When chromatids are separated during anaphase, how do we know that the microtubules that they are connected to are not actually shortening to "pull" the chromatids apart?
