The complex of DNA and protein that makes up a eukaryotic chromosome is properly called:
A
histone
B
centromere
C
chromatin
D
nucleosome
Verified step by step guidance1
Understand the components involved in eukaryotic chromosomes: DNA and proteins, primarily histones.
Recall that histones are proteins around which DNA winds, forming a structural unit called a nucleosome.
Recognize that nucleosomes are the repeating units of DNA wrapped around histones, but not the entire complex.
Identify that the entire complex of DNA and protein (including nucleosomes and other proteins) that makes up the chromosome is called chromatin.
Differentiate chromatin from other terms: histone (protein only), centromere (chromosome region), and nucleosome (DNA-histone unit).
