Answer 1

The cell cycle includes the G1, S, G2, and M phases, with the most DNA present after the S phase and the cell smallest after the M phase. Growth occurs during G1, S, and G2, with the S phase crucial for DNA synthesis before mitosis.

Step-by-step explanation:

The four phases of the cell cycle, in order, are G1, S (Synthesis phase), G2 (Second Growth phase), and M (Mitotic phase). A cell contains the most DNA after the S phase of the cell cycle, because this is when DNA replication occurs. A cell is smallest in size after the M phase because it has just divided into two daughter cells. Growth occurs in the G1, S, and G2 phases of the cell cycle, as the cell increases in size, replicates its DNA, and prepares for mitosis, respectively.


A cell does not enter mitosis until it has completed DNA synthesis, which occurs during the S phase. Growth and preparation for cell division characterize these interphase stages, leading up to the cell division processes of mitosis and cytokinesis.
