A disease is caused by having no functional protein produced from the Kip gene An individual is found to have the disease but does not have a mutation in the Kip gene You look at other gene candidates whose alteration could result in no functional kip protein A gene called D5 codes for a methyltransferase that methylates the Kip promoter region A gene called T3 codes for an acetylase that acetylates the histones in the region of the Kip gene Remember the consequences of acetylation and methylation and fill in the following blanks To generate a scenario in which no Kip protein is made it is likely that the D5 gene has a mutation that results in of the D5 protein or that the T3 gene has a mutation that results in of the T3 protein hyper activation

Rafael was diagnosed with malignant melanoma Sequencing of his tumor genome after biopsy revealed the presence of an activated oncogene targeted by an anti breast cancer drug Although this treatment suppressed tumor growth for a while eventually the tumor stopped responding to the drug and Rafael died The reason for his death most likely was that O Treating one tumor type with a drug developed for another tumor type has a low chance of success O Oncogenes do not stimulate tumor growth tumor suppressors do that O Another mutation probably occurred in the already activated oncogene that made it resistant to the drug O The drug harmed non tumor cells that were suppressing growth of his tumor Malignant cancer cells have multiple mutations driving tumor growth additional driver mutations probably O occurred in his tumor cells that caused resumption of uncontrolled cell proliferation in spite of the action of the drug

p53 is a tumor suppressor gene mutations in p53 are seen in more than 50 of all cancers Which of the following mutations in p53 would likely increase cell division rate predisposing an individual to cancer Sort each mutation into the correct bin to identify it as more likely to be cancer causing or more likely to be non cancer causing A translocation that puts the p53 gene near an active repressor region of DNA such that p53 is not transcribed Duplication of the p53 gene Deletion of one copy of the p53 gene Methylation of CpG islands near the p53 promoter region A nonsense mutation close to the start codon of p53 such that no functional p53 protein is made A missense mutation in the p53 gene that increases the activity of the p53 protein Cancer causing Non cancer causing

Answer the following questions about mutations that lead to cancer Part 1 An individual inherits a cancer predisposing mutation and in adulthood is diagnosed with cancer Consider the individual s inherited genotype If the mutation is in a tumor suppressor gene is the individual likely to be heterozygous or homozygous for the inherited mutation O Heterozygous O Homozygous O Either is equally likely Part 2 An individual has a cancer where one of the key drivers is an oncogene At the genotypic level which is most likely O The individual inherited one copy of the oncogene O The individual inherited two copes of the oncogene O In the tissue where the cancer started a gain of function mutation occurred in a proto oncogene to create this oncogene In the tissue where the cancer started a loss of function mutation occurred in a proto oncogene to create this oncogene

Glucocorticoids are steroid hormones that influence our experience of stress When the promoter of the glucocorticoid receptor gene is methylated in mice they experience higher stress levels and do not nurture their offspring When mice born to high stressed mothers were raised by nurturing mothers rather than their genetic mothers the offspring produced more glucocorticoid receptor protein than mice raised by high stressed mothers The increase in the amount of glucocorticoid receptor protein produced in the mouse offspring is likely because the nurturing expression of the gene methylation of the gene s promoter region which led to behavior cause increased decreased

Which of the following statements is are consistent with scientists observations about epigenetics O Individuals can pass on a methylation state only if it has an evolutionary advantage O Environmental conditions can result in methylation of promoter regions of particular genes The methylation state of a gene is copied every time DNA is replicated Many promoter sequences are susceptible to methylation which decreases transcription of those genes

A reciprocal translocation between Chromosome 9 and Chromosome 22 produces the so called Philadelphia chromosome which causes chronic myelogenous leukemia CML a cancer of white blood cells The translocation results in production of a protein that is no longer regulated but rather always active This leads to uncontrolled cell division in white blood cells Although this cancer always involves translocations between chromosomes 9 and 22 the BCR ABL protein that is the result of this translocation can vary in size contains 185 220 amino acids because the exact DNA bases where the chromosome breaks can vary Part 1 In any ONE patient will the BCR ABL fusion proteins isolated from a single tumor be the same size or varying sizes O Same size O Both same and varying sizes are possible O Varying sizes Part 2 If samples are taken from 100 patients will the BCR ABL protein in the cancerous white blood cells be the same size or of varying sizes Pick the most likely answer O All patients will have an BCR ABL protein of the same size O All patients will have BCR ABL proteins of varying sizes O Some patients may have the same size others will have varying sizes of the BCR ABL protein
