alleryA nucleosome consists of
A200 bp of DNA wrapped around an octamer of histones
B100 bp of DNA wrapped around a tetramer of histones
C200 bp of RNA wrapped around four histones
DDNA without any protein
Answer & Solution
Correct answer: A. 200 bp of DNA wrapped around an octamer of histones
**A nucleosome is the basic packing unit:** ~200 bp of DNA wound around a core of eight histone proteins (the histone octamer).
Strings of nucleosomes form the chromatin fibre.
