The duration of the cell cycle is decreased in response to increased amounts of
A)telomerase.
B)cyclin
C)DNA helicase.
D)proteasome.

Question

Quizplus · Accepted Answer

Cyclin is a protein that regulates the cell cycle by activating cyclin-dependent kinases (CDKs). Increased amounts of cyclin can lead to faster progression through the cell cycle, resulting in a decrease in the duration of the cell cycle.

The other choices are not directly involved in regulating the duration of the cell cycle. Telomerase is involved in maintaining the length of telomeres at the ends of chromosomes, DNA helicase is involved in unwinding DNA during replication, and the proteasome is involved in protein degradation.
