During embryonic development, the total cell cycle time for a given cell type can change. These changes are primarily due to variation in
Options
- AG 1 phase
- BG 2 phase
- CM phase
- DS phase
Correct answer
A. G 1 phase
Step-by-step solution
The division cycle of most cells consists of four coordinated processes: cell growth, DNA replication, distribution of the duplicated chromosomes to daughter cells, and cell division. During G 1 , the cell is metabolically active and continuously grows but does not replicate its DNA. G 1 phase is the most variable phase of the cell cycle as far as the duration of the phase is concerned. It is the longest phase of interphase.
