MITOSIS AND MEIOSIS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In what part of the Cell Cycle does the cell grow and replicate DNA?
A
Interphase
B
Mitosis
C
Meiosis
D
Cytokinesis
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: -Interphase is the longest part of the cell cycle. This is when the cell grows and copies its DNA before moving into mitosis. During mitosis, chromosomes will align, separate, and move into new daughter cells. The prefix inter-means between, so interphase takes place between one mitotic (M) phase and the next.

Detailed explanation-3: -In the eukaryotic cell cycle, chromosome duplication occurs during “S phase” (the phase of DNA synthesis) and chromosome segregation occurs during “M phase” (the mitosis phase).

Detailed explanation-4: -The G1 phase stands for gap 1 and is when organelles replicate and the cell grows. The S phase stands for synthesis and is when DNA is replicated.
