Question

M-cyclin levels begin to rise in _____ phase, and reach a maximum in _____ phase.

a) G1, G2
b) S, M
c) G2, M
d) S, G1

Answer 1

M-cyclin levels begin to rise in G1 phase and reach a maximum in G2 phase.

Step-by-step explanation:

The cell cycle is a series of events that take place in a eukaryotic cell, leading to its division and the duplication of its genetic material. This cycle consists of distinct phases, each with specific activities and checkpoints to ensure accurate and controlled cell division. The cell cycle is crucial for growth, development, tissue repair, and the maintenance of multicellular organisms.

M-cyclin levels begin to rise in G1 phase, and reach a maximum in G2 phase.
