How many chromosomes will the diploid cell have at G1, after S and after M-phase respectively if the haploid cell has 7 chromosomes?
Options
- A7,7 , 14
- B7 , 14 , 14
- C14 , 14 , 14
- D7 , 7 , 7
Correct answer
C. 14 , 14 , 14
Step-by-step solution
Cell division consists of interphase and mitotic phase. The interphase consists of G 1 , S and G 2 phases. If M phase is mitosis then all the phases of interphase will have the diploid ploidy level. Thus G 1 , S and G 2 will have 2n chromosomes i.e. 14 chromosomes.
