Question

at the restriction point (r), cyclin-dependent kinases (cdks) catalyze the phosphorylation of targeted proteins, a process that changes the charge and shape of the targeted proteins turning the proteins on/off. as a result, the cell cycle progresses from ________.
○ s to m
○ m to g1
○ g2 to m
○ g1 to g2
○ g1 to s

Explanation:

The restriction point (R) is located in the G1 phase of the cell cycle. Once a cell passes this point, it commits to progressing through the rest of the cell cycle, moving from the G1 phase into the S (synthesis) phase where DNA replication occurs. Cyclin-dependent kinases (CDKs) at this point drive this transition via protein phosphorylation.

Answer:

G1 to S
