The centriole undergoes duplication during:
The centriole undergoes duplication during:
Options
- AS-phase
- BProphase
- CMetaphase
- D phase
Correct answer
A. S-phase
Step-by-step solution
Centrioles undergo duplication during the S phase of the interphase and begin to move towards the opposite pole of the cell during the prophase stage of mitosis.
S phase is the period of DNA synthesis during which the cell replicates its genetic content; a normal diploid somatic cell with a 2c complement of DNA at the beginning of the S phase acquires a 4c complement of DNA at its end.
