Which of the following statements describes a eukaryotic chromosome? a) a single strand of dna b) a series of nucleosomes wrapped around two dna molecules c) a chromosome with different numbers of genes in different cell types of an organism d) a single linear molecule of double-stranded dna plus proteins

The correct statement is D) a single linear molecule of double-stranded DNA plus proteins.

Explanation:

A chromosome is understood as the organized genetic material. In the case of eukaryotic organisms, the chromosome is born primarily from the interaction between DNA, histones (proteins) and non-histonic proteins. Eukaryotic chromosomes are very long molecules of double helix DNA (The DNA of each chromosome is a long chain of double-stranded DNA) in interaction with proteins (histones and non-histones) that can be found from relaxed or poorly compacted states.
