Abnormal chromosomes are frequently found in malignant tumors. Errors such as translocations may place a gene in close proximity to different control regions that could result in which of the following events?

Question

a decrease in mitotic frequency
expression of genes that lead to inappropriate cell division
an increase in nondisjunction
failure of the cancer cells to multiply

Answer 1

The correct answer is:

expression of genes that lead to inappropriate cell division.

Translocations can result in certain genes being placed next to regulatory elements that can overactivate those genes, leading to uncontrolled cell division, which is a hallmark of cancer cells.
