Detailed explanation-1: -a) True, the interphase and mitosis together constitute the cell cycle. The nuclear membrane is formed around the newly-formed sets of daughter chromosomes during the telophase.

Detailed explanation-2: -The cell cycle is composed of interphase (G₁, S, and G₂ phases), followed by the mitotic phase (mitosis and cytokinesis), and G₀ phase.

Detailed explanation-3: -Answer: The correct option for this question is option C) The timing of the cell division is usually combined by the cyclins and CDKs.

Detailed explanation-4: -Both mitosis and meiosis are multistage processes. The stages are interphase, prophase, metaphase, anaphase and telophase. The same general processes occur in each of these stages for mitosis and meiosis. Interphase is cell growth and DNA replication in preparation for cell division.

Detailed explanation-5: -A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division.
