Interphase

Detailed explanation-1: -Answer and Explanation: In meiosis, DNA replication occurs only once, whereas the cells divide twice, and it is the mechanism that produces genetic variation in daughter cells. This statement is true. DNA replication occurs in interphase before the first meiotic cycle occurs.
Detailed explanation-2: -M phase (mitosis) is usually followed by cytokinesis. S phase is the period during which DNA replication occurs.
Detailed explanation-3: -Mitosis is a fundamental process for life. During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells. Because this process is so critical, the steps of mitosis are carefully controlled by certain genes.
Detailed explanation-4: -Cells must replicate their DNA before they can divide. This ensures that each daughter cell gets a copy of the genome, and therefore, successful inheritance of genetic traits.
