Question

what is G1 phase............​

Answer 1

Explanation:

The g1 phase, Gap 1 phase, or Growth 1 phase, is the first of four phases of the cell cycle that takes place in eukaryotic cell division. In this part of interphase, the cell synthesizes mRNA and proteins in preparation for subsequent steps leading to mitosis.

Answer 2

Explanation:

G-Phase (First growth or Gap phase, Pre synthetic phase)

It is the Longest phase of cell cycle but most variable in length. Cell and nucleus grow in size. In middle of G, phase (Restriction point) a cell has two options. Stop cell cycle and enter G, phase for undergoing differentiation or Continue cycle and enter S-phase by taking decision of division with the help of growth-dependent cyclin-dependent kinase (CDK). It's activity promotes DNA replication and initiates G1-to-S phase transition.
