This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: Structure and function of protein, Subject name: Biochemistry
True-regarding DNA-replication are all except 
Select and explain. 
A. Occurs in the M-phase of the cell cycle, B. Sister Chromatids are formed, C. Follow base pair rule, D. Semi conservative
A: Occurs in the M-phase of the cell cycle
Answer: A: Occurs in the M-phase of the cell cycle 
Explanation: *Occurs during S phase of cell cycle, In the S phase (S for synthesis) chromosomal DNA is replicates *It occurs at many chromosomal origins, is bi-directional and semi-conservative *Follows the base pair rule: The sequence of the daughter strand is dictated by the parental strand; an A in the parental strand causes a T to be placed in the daughter strand, a parental G directs incorporation of a daughter C, and so on Ref : Biochemistry by U.
