Question

What is the constituency of telomeres of eukaryotic chromosomes?

Answer 1

Telomeres:

1. A telomere is a chromosome's terminal portion.
2. Telomeres are non-coding DNA regions that safeguard chromosomes from damage by repeating themselves.
3. They shorten with each cell division.
4. They eventually reach to the point where they can't divide in the cell anymore.
5. Each chromosome has two telomeres, for a sum of 92 telomeres on all 46 chromosomes.
6. They prevent genetic ends from fraying or coming together, much like the plastic tips on the ends of shoelaces.
7. Telomeres also play a role in ensuring that our DNA is accurately replicated while our cells divide.
8. Small sections of guanine-rich repeats are repeated frequently in the telomeres of eukaryotic chromosomes.
9. Telomeres are physically and functionally highly conserved in eukaryotes.
10. Telomeric DNA is made up of basic and randomly repeated sequences.
