Question

Which is not true about the chromosomes of a multicellular organism ?

• A. They are made up of DNA and protein
• B. Each chromosome is replicated into two chromatids during the S-phase of interphase
• C. Each chromosome separates into two daughter chromosomes by binary fission
• D. All cells contain chromosomes that carry the same genetic information

Answer 1

The correct option is C Each chromosome separates into two daughter chromosomes by binary fission

During binary fission, each cell separates into two separate daughter cells. Chromosomes are duplicated before cell division and each daughter cell get half of the chromosomes. Hence each chromosome is not separated rather chromosomes are divided between two daughter cells quantitatively.

So, the correct option is 'Each chromosome separates into two daughter chromosomes by binary fission'.
