Detailed explanation-1: -The cell cycle has two major phases: interphase and the mitotic phase (Figure 6.3). During interphase, the cell grows and DNA is replicated.

Detailed explanation-2: -At the molecular level, however, interphase is the time during which both cell growth and DNA replication occur in an orderly manner in preparation for cell division.

Detailed explanation-3: -There is some kind of growth happening inside the cell during the interphase. Hence the statement “There is no cell growth” is an incorrect statement.

Detailed explanation-4: -During interphase, the cell grows and the nuclear DNA is duplicated. Interphase is followed by the mitotic phase. During the mitotic phase, the duplicated chromosomes are segregated and distributed into daughter nuclei. The cytoplasm is usually divided as well, resulting in two daughter cells.

Detailed explanation-5: -During the S phase of the cell cycle, DNA replication occurs at the interphase. There are four stages in the cell cycle i.e. G1, S, G2, and M. DNA replicates before actual cell division so that identical set of the genome of the parent cell is received by each daughter cell.
