Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which part of the cell cycle ensures that an identical copy of the original DNA of the parent is made?
A
G1
B
G2
C
S
D
Mitosis
Explanation: 

Detailed explanation-1: -During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells.

Detailed explanation-2: -Anaphase ensures that each daughter cell receives an identical set of chromosomes, and it is followed by the fifth and final phase of mitosis, known as telophase.

Detailed explanation-3: -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-4: -Interphase: Each chromosome undergoes replication, making an identical copy of itself. At this point, the chromosomes are still long and thin, and are not visible inside the nucleus. Cells spend most of their life in this non-dividing phase.

Detailed explanation-5: -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).
