Question

Which phase of the cell cycle occurs first? S phase interphase mitosis G1 phase

Answer 1

the mitosis cycle first starts in the G1 phase, then the S phase, and finally the G2 phase.

Answer 2

The correct answer is the G1 phase.

Explanation:

The cell cycle includes two major stages or phase interphase and M-phase. Interphase is divided into three different phases which are G1 phase, S phase, and G2 phase. M- phase is of two closely joint stages karyokinesis and cytokinesis.

G1 phase is the first phase of the cell cycle, the cell produces a variety of proteins that are essential for DNA replication.

Thus, the correct answer is G1.
