Questions: Which animal cells divide by mitosis?

To address the questions provided:

1. Separation of replicated chromosomes: The answer is "Mitosis."

   • Explanation: During mitosis, replicated chromosomes are separated into two new nuclei. This process ensures that each daughter cell receives an identical set of chromosomes.

2. Replication of DNA: The answer is "S phase of the cell cycle."

   • Explanation: DNA replication occurs during the S phase (Synthesis phase) of the cell cycle, which is part of interphase. This is when the cell duplicates its DNA in preparation for cell division.

3. Which animal cells divide by mitosis? The answer is "Somatic cells."

   • Explanation: In animals, somatic cells (non-reproductive cells) divide by mitosis. This process is responsible for growth, development, and tissue repair. In contrast, reproductive cells (gametes) are produced through meiosis.

In summary, mitosis is responsible for the separation of replicated chromosomes, DNA replication occurs during the S phase, and somatic cells in animals divide by mitosis.
