Which of the following occurs more than one and less than five in a chromosome : -Each linear chromosome has two ends, and each end carries a telomere. So a chromosome has two telomeres (or four, counting both chromatids of a duplicated chromosome), i.e. more than one and less than five.
A chromosome normally has only one centromere.
Chromomeres are bead-like condensed regions along a chromosome, and their number is very large.
Chromatids are two per duplicated chromosome, but the answer key considers telomeres here.
So, as per the answer key, telomeres occur more than one and less than five in a chromosome.
