Which of the following statements describes the eukaryotic chromosome?
A)It is composed of DNA alone.
B)The nucleosome is its most basic functional subunit.
C)The number of genes on each chromosome is different in different cell types of an organism.
D)It consists of a single linear molecule of double-stranded DNA.
E)Active transcription occurs on heterochromatin.

Question

Quizplus · Accepted Answer

The eukaryotic chromosome consists of linear DNA molecules that are double-stranded. This is unique from the circular DNA molecules found in prokaryotic chromosomes.

Note: Options A, B, C, and E are all incorrect. A eukaryotic chromosome is composed of both DNA and protein, with the nucleosome being the basic unit of chromatin. The number and arrangement of genes on a chromosome are specific to each species, not cell type, and active transcription occurs in euchromatin, which is less condensed than heterochromatin.
