Q1. Which of the following is not a part of a chromosome?

A Satellite

B F1 particle Correct

C Centromere

D Chromatid

Explanation

A chromosome may have chromatids, a centromere and, in some chromosomes, a satellite separated by a secondary constriction. These are structural parts or recognised regions of chromosomes. An F1 particle, however, is not a chromosomal component; it is associated with ATP synthase in cell organelles such as mitochondria and chloroplasts. Therefore it is outside chromosome structure. Satellite, centromere and chromatid all belong to chromosome morphology, so they cannot be the item that is not part of a chromosome.
