DNA synthesis is seen in which phase of cell cycle? 
Select and explain. 
A. Resting phase, B. Synthetic phase, C. Mitotic phase, D. Premitotic phase
B: Synthetic phase
Answer: B: Synthetic phase 
Explanation: * Cell cycle is defined as the sequence of events that causes cell division.* It consists of following phases:# G1 phase (Presynthetic growth)# S phase (DNA synthesis)# G2 (Premitotic growth), and# M phase (mitotic).# Quiescent cells that are not actively cycling are said to be in the G0 state. Cells can enter G1 either from the G0 quiescent cell pool, or after completing a round of mitosis, as for continuously replicating cells.
