Question

When does mitosis start?

A. during the cellular respiration process
B. during the photosynthesis process
C. after the lysosome removes a virus
D. after interphase when the cell grows
E. after the DNA doubles/copies itself"

Answer 1

Mitosis begins after the cell has completed the three stages of interphase: G1, S phase, and G2. During the mitotic phase, the cell undergoes four stages of mitosis followed by cytokinesis resulting in two new daughter cells. The correct option is D. after interphase when the cell grows

Step-by-step explanation:

Mitosis starts after interphase when the cell has grown and prepared itself for cell division. Interphase consists of three stages: G1 (cell growth and protein synthesis), S phase (DNA replication), and G2 (further growth and preparation for division). Once these stages are completed, the cell then enters the mitotic phase, which is when actual mitosis occurs.

This phase of the cell cycle comprises four stages of mitosis (prophase, metaphase, anaphase, and telophase) and ends with cytokinesis, where the cell body divides to form two new cells. The entire process ensures that each daughter cell receives an identical set of chromosomes, and the DNA in these daughter cells is identical to that of the parent cell. The correct option is D. after interphase when the cell grows
