THE CELL CYCLE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What does G1 stand for?
A
First growth phase
B
Ground phase
C
Regrowth phase
Explanation: 

Detailed explanation-1: -G1 phase (G stands for gap) spans from the end of mitosis to the start of S phase. During G1 phase, cells check the external environment and the intracellullar state, and decide if they continue with the cell cycle or not.

Detailed explanation-2: -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.

Detailed explanation-3: -The first part of interphase is called the first gap phase (G1). Cell growth marks the G1 phase of the cell cycle.

Detailed explanation-4: -The G1 stage stands for “GAP 1". The S stage stands for “Synthesis". This is the stage when DNA replication occurs. The G2 stage stands for “GAP 2". The M stage stands for “mitosis", and is when nuclear (chromosomes separate) and cytoplasmic (cytokinesis) division occur.
