Question

A body cell of an organism has 8 chromosomes. Which describes the chromosome composition of one of the body cells after interphase?

• A. Sixteen chromosomes made up of 16 chromatids
• B. Sixteen chromosomes made up of 8 chromatids
• C. Eight chromosomes made up of 8 chromatids
• D. Eight chromosomes made up of 16 chromatids
• E. Four chromosomes made up of 8 chromatids

Answer 1

The correct option is D Eight chromosomes made up of 16 chromatids

The number of chromosome present in a cell is given as 8. Each chromosome is represented by 1 chromatid. During the process of cell division, the genetic material gets doubled. This means that the number of chromosome remains same, only the number of chromatids and the number of DNA molecules gets doubled. So, the number of the chromosome will remain same as 8 and the number of chromatid gets doubled to 16.

So, the correct answer is option D.
