THE CELL CYCLE

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: -During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells.

Detailed explanation-3: -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-4: -Interphase is the most important stage of cell cycle. The cell stays in the interphase for maximum periods. During this phase the cell prepares itself for division. The cell undergoes cell growth and replication during this phase.

Detailed explanation-5: -In the S phase (synthesis phase), DNA replication results in the formation of two identical copies of each chromosome-sister chromatids-that are firmly attached at the centromere region.
