Question

Quizplus · Accepted Answer

Chromosomes in eukaryotic cells are composed of DNA wrapped around proteins called histones, which together form a structure called chromatin. This chromatin is further coiled and condensed to form the characteristic chromosome shape seen during cell division. Therefore, chromosomes in eukaryotic cells contain both DNA and proteins. RNA and phospholipids do not play a structural role in chromosomal composition.
