CELL DAMAGE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Cells undergo cell division, which involves both mitosis and cytokinesis.
A
G1
B
S
C
G2
D
M phase
Explanation: 

Detailed explanation-1: -Cell division occurs during M phase, which consists of nuclear division (mitosis) followed by cytoplasmic division (cytokinesis). The DNA is replicated in the preceding S phase; the two copies of each replicated chromosome (called sister chromatids) remain glued together by cohesins.

Detailed explanation-2: -Eukaryotic Cell Cycle The mitotic phase (M) includes both mitosis and cytokinesis. This is when the nucleus and then the cytoplasm divide. The other three phases (G1, S, and G2) are generally grouped together as interphase. During interphase, the cell grows, performs routine life processes, and prepares to divide.

Detailed explanation-3: -The M phase consists of mitosis and cytokinesis. Mitosis is the process in which DNA condenses into visible chromosomes, which is followed by the separation of the chromosomes into two identical sets.

Detailed explanation-4: -Mitosis, or M phase, is the period of actual nuclear and cell division during which the duplicated chromosomes are divided equally between two progeny cells.

Detailed explanation-5: -Mitosis (the M phase) The process of mitosis, or cell division, is also known as the M phase. This is where the cell divides its previously-copied DNA and cytoplasm to make two new, identical daughter cells. Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase.
