Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The first stage of the cell cycle during which the cell matures and prepares to divide and copies its DNA
A
interphase
B
prophase
C
metaphase
D
anaphase
Explanation: 

Detailed explanation-1: -During interphase, the cell grows and makes a copy of its DNA. During the mitotic (M) phase, the cell separates its DNA into two sets and divides its cytoplasm, forming two new cells.

Detailed explanation-2: -Cell cycle has different stages called G1, S, G2, and M. G1 is the stage where the cell is preparing to divide. To do this, it then moves into the S phase where the cell copies all the DNA.

Detailed explanation-3: -The cell cycle has two major phases: interphase and the mitotic phase ([link]). During interphase, the cell grows and DNA is replicated. During the mitotic phase, the replicated DNA and cytoplasmic contents are separated, and the cell divides. The cell cycle consists of interphase and the mitotic phase.

Detailed explanation-4: -Interphase is the period when a cell is getting ready to divide and start the cell cycle. During this time, cells are gathering nutrients and energy. The parent cell is also making a copy of its DNA to share equally between the two daughter cells.

Detailed explanation-5: -The first stage of interphase is called the G1 phase (first gap) because, from a microscopic aspect, little change is visible. However, during the G1 stage, the cell is quite active at the biochemical level.
