2017 Molecular Basis of InheritancePackaging of DNA – nucleosome Medium Question 90 of 200 in Molecular Basis of Inheritance

The association of histone H1 with a nucleosome indicates:

A Transcription is occurring
B DNA replication is occurring
C The DNA is condensed into a Chromatin Fibre
D The DNA double helix is exposed

The answer is C.

Solution

H1 linker histone promotes chromatin condensation.

The association of H1 protein indicates complete formation of the nucleosome. Therefore the DNA is in condensed form (chromatin fibre).

Concept histone-h1-condensation
