Which is the longest of the mitosis cell cycle?
Correct answer: D. Interphase
- A. Telophase
- B. Anaphase
- C. Metaphase
- D. Interphase
Explanation
Interphase is the longest stage of the cell cycle, encompassing the period between cell divisions. During interphase, the cell grows, carries out its normal functions, and replicates its DNA in preparation for cell division. Interphase can be further divided into three sub-phases: G1 (Gap 1), S (Synthesis), and G2 (Gap 2). During G1, the cell grows and carries out its normal functions. In the S phase, DNA replication occurs, resulting in the synthesis of two identical copies of each chromosome. Finally, during G2, the cell continues to grow and prepares for cell division by synthesizing proteins necessary for mitosis or meiosis.
