Centromere is required for (a) Movement of chromosomes towards poles (b) Cytoplasmic cleavage (c) Crossing over (d) Transcription |
|
Answer» The correct option is (a). Explanation: Centromere is the point at which the two chromatids of a chromosome are held together. During movement of chromosomes, the spindle fibres (on which the chromatids move) are attached to the centromere. Crossing over involves physical exchange of genetic j material between non-sister chromatids of homologous ; chromosomes. Cytoplasmic cleavage is the division of cytoplasm. Transcription is the process in which the genetic ; information of DNA is transferred to wRNA as the first step in protein synthesis. |
