Question

What is the constituency of telomeres of eukaryotic chromosomes?

Answer 1

The degrees of packing from raw DNA molecules to chromosomal structures which are seen during mitosis or meiosis are referred to as eukaryotic chromosomes.

Complete answer:
A telomere is the chromosome's terminus. Telomeres are made up of non-coding DNA sequences that preserve the chromosomes from harm by repeating themselves. Telomeres shorten with each cell division. They eventually get so short that they stop dividing the cell.
Each chromosome has two telomeres, for a total of 92 telomeres across all 46 chromosomes.
Their purpose is to keep chromosomal ends from fraying or sticking together, similar to the plastic tips on the ends of shoelaces. Telomeres are also crucial in ensuring that our DNA is correctly replicated as cells divide.
In the telomeres of eukaryotic chromosomes, there are small stretches of guanine-rich repeats that are repeated repeatedly. Telomeres are highly conserved in eukaryotes, both structurally and functionally. Telomere DNA consists of simple and randomly repeated sequences, as may be observed. Each strand has a clustered arrangement of C and G residues, with C residues in the first strand, and G residues in the second. Telomeres also have a short stretch of G-rich strands approximately 12-16 nucleotides in length.

Note:
Chromosome DNA coils and condenses around nuclear proteins called histones to form a chromosome in eukaryotes. A cell's nucleus contains eukaryotic chromosomes. Nuclear DNA is stored in this nucleus and acts as the cell's control centre. To govern molecule flow into and out of the nucleus, the nuclear membrane or the nuclear envelope has channels called pores.
