CELL DAMAGE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which stage of the cell cycle is MOST critical for ensuring that daughter cells are identical?
A
G1
B
S
C
Prophase
D
G2
Explanation: 

Detailed explanation-1: -Mitosis is used to produce daughter cells that are genetically identical to the parent cells. The cell copies-or ‘replicates’-its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set.

Detailed explanation-2: -Metaphase is the third phase of mitosis, the process that separates duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells.

Detailed explanation-3: -During anaphase, the sister chromatids are separated simultaneously at their centromeres. The separated chromosomes are then pulled by the spindle to opposite poles of the cell. Anaphase ensures that each daughter cell receives an identical set of chromosomes.

Detailed explanation-4: -The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells.

Detailed explanation-5: -The most important stage of the cell cycle is interphase, for several reasons. One reason is that during interphase, the cell prepares itself for cell division. The cell also undergoes cell growth and replication during interphase.
