Which of the following occurs more than one and less than five in a chromosome?
Which of the following occurs more than one and less than five in a chromosome?
Chromatid
Chromomere
Centromere
Telomere
Solution
Each of the chromatids is capped with the telomere structure on either end of each arm. Therefore, a single chromosome in metaphase would have four total telomeres, two on each sister chromatid. Each chromosome consists of two chromatids and one centromere. Chromomeres form from the local coiling of a continuous DNA thread. There are more than 2000 chromomeres on 20 chromosomes of maize.
Related Theory
A telomere is the end of $a$ chromosome. Telomeres are made of repetitive sequences of non-coding DNA that protect the chromosome from damage. Each time a cell divides, the telomeres become shorter. In humans the telomere sequence is TTAGGG.
