Question

What type of DNA is most likely to be found in heterochromatin?

Answer 1

Heterochromatin:

1. Heterochromatin is compactly coiled regions of the chromatin and is found in the centromere and telomere of a chromosome.
2. Heterochromatin contains more DNA and replicates at the end of the S-phase of the mitotic cycle.
3. In, heterochromatin, satellite DNA is the type of DNA that is most likely to be found.
4. Satellite DNA is the one that has more repetitive short sequences that are repeated a large number of times.
5. Satellite DNA is the non-coding region of DNA found in eukaryotes.
6. It is genetically inert because of the presence of satellite DNA and does not transcribe. Thus, are also not involved in protein synthesis.
