alleryA typical nucleosome contains approximately how many base pairs of DNA?
A100
B1000
C50
D200
Answer & Solution
Correct answer: D. 200
A nucleosome = histone octamer + **~200 bp of DNA** wrapped around it.
Linker DNA between nucleosomes is ~50 bp.
Under EM, chromatin appears as 'beads-on-a-string'.
