Question

which process occurs during prophase of mitosis in an animal cell
a)division of centromeres
b)formation of chromosomes
c)replication of DNA
d)separation of centrioles​

Answer 1

Explanation:

d separation of centrioles

Answer 2

The separation of centrioles near the nucleus begins during the prophase of mitosis in an animal cell. (Option d)

• Mitosis begins with the prophase, which is the longest phase. A nuclear envelope is destroyed during prophase as the chromatin condenses into chromosomes.
• The centrioles are small organelles that are only found in eukaryotic cells. They help ensure the new cells produced after cellular division maintain a complete set of chromosomes.
• A spindle forms between the centrioles as they move apart.
• Chromatin, the complex of DNA and proteins located within the nucleus, condenses during prophase.
• As a result of nucleoli breakdown in prophase, ribosome production ceases.
