Question

A somatic cell that has just completed the S-phase of the 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 and four times 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.

Answer 1

Answer: (C)

twice the number of chromosomes and four times the amount of DNA

The amount of DNA and chromosome number of a somatic cell that had just completed the S-phase of its cell cycle have 4 times more DNA content and twice the number of chromosome as compared to the gametes of the same species. In general, a gamete is haploid. A somatic cell is diploid.

So, the correct option is 'twice the number of chromosomes and twice the amount of DNA'
