Answer to Question 1

Answer: The most common epigenetic change in the development of cancer involves a methylation/demethylation of CpG dinucleotide bases. Cancer can involve demethylation of promoter regions of genes making them transcriptionally ready. Methylation can result in transcriptional silencing of the gene and loss of function of tumor suppressor genes. Deacetylation of key histones can result in gene silencing which may favor growth over differentiation.

Answer to Question 2

Correct answer: B
