Quizplus · Accepted Answer

Nucleosomes are spaced along chromosomal DNA at intervals of approximately 200 nucleotides, but the question asks for low concentration digestion, which typically results in fragments around 180-200 nucleotides, closest to 60 nucleotides when considering the core nucleosome DNA.
