- Bcrossing over
- Ccytoplasmic cleavage
- Dmovement of chromosomes towards poles
Correct answer
D. movement of chromosomes towards poles
Step-by-step solution
Chromosomes are responsible for the transmission of the hereditary information from one generation to the next. The arms of chromosome is known as chromatids. These arms are held together at a point called the centromere (or primary constriction). Centromere occurs any where along the length of chromosome. During cell division spindle fibres are attached to centromere and help in the movement of chromosomes towards the poles.
