A) amount of DNA doubles in each cell
B) amount of DNA remains same in each cell
C) chromosome number is increased
D) amount of DNA is reduced to half in each cell
Correct Answer: A
Solution :

DNA replication along with the synthesis of histone proteins results in the duplication of chrombsomal material i.e., amount of DNA doubles in each cell. Amount of DNA remains unchanged during \[{{G}_{1}}\] phase or post mitotic gap and/or \[{{G}_{2}}\] phase or pre mitotic phase. |
