Which of the followings does not occur in the interphase of eukaryotic cell division?
Increase of ATP synthesis
Increase of DNA synthesis
Increase of RNA synthesis
Reduction in cell size
D.
Reduction in cell size
Interphase is the living phase of the cell. Here, cell spends its majority of time and prepares itself for cell division. This increases its size and makes a copy of its DNA. Majority of eukaryotic cells spends most of their time in interphase.
