Both mitosis and meiosis begin after the chromosomes have been duplicated during interphase.?

Question

True or False?

Answer 1

True.

Interphase encompasses all of the parts of the cell cycle outside of mitosis and meiosis. In particular, the synthesis or S phase where all chromosomal DNA is replicated is part of interphase. Cellular checkpoints for the completion of DNA duplication are made before the cell commits to either mitosis or meiosis.

Remember: G1-->S-->G2-->M

Prophase does not IMMEDIATELY follow the duplication of DNA. G2 (Gap 2) is where the cell makes sure its ready to enter mitosis or meiosis.

Answer 2

False. Interphase has nothing to do with chromosome duplication. In fact, the interphase is a time when nothing happens in the cell.

Answer 3

true

there DNA doubles

then step into prophase
