PATHOLOGY

Detailed explanation-1: -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-2: -G1 is the stage where the cell is preparing to divide. To do this, it then moves into the S phase where the cell copies all the DNA. So, S stands for DNA synthesis.

Detailed explanation-3: -The first stages of the cell cycle involve cell growth, then replication of DNA . The single strand of DNA that makes up each chromosome produces an exact copy of itself. All of the organelles inside the cell are also copied. These processes happen in a stage of the cell cycle called interphase .

Detailed explanation-4: -The stages of interphase are: G1 (Gap 1), in which the cell grows and functions normally. During this time, a high amount of protein synthesis occurs and the cell grows (to about double its original size) – more organelles are produced and the volume of the cytoplasm increases.
