A few chromosomes have non-staining constrictions at a constant location. What are these constrictions called? Correct Answer Satellite

Some chromosomes have secondary constrictions which are non – staining, apart from the centromere. They give the appearance of a small fragment. This small fragment is known as a satellite.

Read the given information carefully and answer the questions related to it. The eight friends A, B, C, D, E, F, G and H are sitting in the center of a circle, (they do not have to be the same). i. The location of A is the third to the right of F, who is sitting on the left of the D on the second number. ii. C and H are sitting face to face with each other. iii. None of F and C are sitting next to B. iv. B is not sitting in between H and A. v. G is seated opposite A. If the location of E is replaced by B, the location of C is shifted from place of G and the location of A is mutual, then who will be the third position on the right of C?
