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: -The part of interphase in which the cell doubles in size and the enzymes, cytoplasmic organelles, and other molecules double in number is the G1 phase. The G1 or Gap 1 phase is the period between the end of mitosis and the start of DNA replication.

Detailed explanation-3: -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.

Detailed explanation-4: -Interphase can be divided into three stages: The first growth phase (G1): During the G1 stage, the cell doubles in size and doubles the number of organelles. The synthesis phase (S): The DNA is replicated during this phase.

Detailed explanation-5: -The G1 phase, gap 1 phase, or growth 1 phase, is the first of four phases of the cell cycle that takes place in eukaryotic cell division. In this part of interphase, the cell synthesizes mRNA and proteins in preparation for subsequent steps leading to mitosis.
