A somatic cell that has just completed the S phase of its cell cycle, as compared to gamete of the same species, has
A
Twice the number of chromosomes and twice the amount of DNA
B
Same number of chromosomes but twice the amount of DNA
C
Twice the number of chromosomes and four times the amount of DNA
D
Four times the number of chromosomes and twice the amount of DNA
Detailed Solution
A somatic cell is diploid (2n, 2C) and a gamete is haploid (n, C).
After S phase the DNA doubles to 4C, but the chromosome number stays 2n.
So compared with a gamete, it has twice the chromosomes and four times the DNA.
After S phase the DNA doubles to 4C, but the chromosome number stays 2n.
So compared with a gamete, it has twice the chromosomes and four times the DNA.
