Question

The N-terminal tail of histone H3 can be extensively modified, and depending on the number, location, and combination of these modifications, these changes may promote the formation of heterochromatin.

What is the result of heterochromatin formation?

A. Increase in gene expression
B. Gene silencing
C. Displacement of histone H1
D. Mutation
E. Recruitment of remodeling complexes

Answer 1

Answer: the correct option is B ( Gene silencing).

Explanation:

Heterochromatin formation is directed by RNA interference a naturally occurring process in the nucleus of eukaryotic cells that silences gene expression. Therefore the result of the heterochromatin formation is gene silencing. Hope this helps. Thanks.
