Question

Quizplus · Accepted Answer

Ubiquitin is a small protein that gets added to other proteins as a signal for proteasomal degradation. In this case, by adding ubiquitin to the tumor suppressor protein p53, HPV is affecting the longevity of the protein, leading to its degradation and decreased levels in the cell. This ultimately affects gene expression at the level of protein activity and function. Therefore, the best choice would be E, protein longevity.
