Question

a scientist prepares two cell cultures: one undergoing mitosis and one undergoing meiosis. in both cultures, dna replication must be completed before division begins. this phase is known as: interphase metaphase cytokinesis prophase an organism begins with a diploid cell (2n) containing 20 chromosomes. this cell proceeds through the entire meiotic process. how many times does the cytoplasm divide (cytokinesis) to form the final products? four times zero times one time two times

Explanation:

• First question:
• In cell division (both mitosis and meiosis), DNA replication occurs in interphase. Metaphase is when chromosomes align. Cytokinesis is cell - division. Prophase is the start of chromosome condensation.
• Second question:
• Meiosis has two rounds of division (meiosis I and meiosis II). Each round has cytokinesis. So, there are two cytoplasmic divisions.

Answer:

• First question: Interphase
• Second question: Two times
