Which of the following statements regarding DNA packing is false?
A)A nucleosome consists of DNA wound around a protein core of eight histone molecules.
B)DNA packing tends to promote gene expression.
C)Highly compacted chromatin is generally not expressed at all.
D)Prokaryotes have proteins analogous to histones.

Question

Quizplus · Accepted Answer

DNA packing can inhibit gene expression by making certain genes less accessible to transcriptional machinery. Highly compacted chromatin is generally not expressed at all, which makes statement C true. A is true because nucleosomes are composed of DNA and histones. D is also true because prokaryotes have DNA-binding proteins that function similarly to histones.
