Eukaryotic Chromosome Structure
Multiple Choice
In eukaryotic cells, what best describes the relationship between chromosomes and DNA?
A
DNA is made of many chromosomes linked end-to-end in the nucleus.
B
A chromosome is a long DNA molecule packaged with histone and other proteins into chromatin.
C
Chromosomes are membrane-bound organelles that synthesize DNA during translation.
D
Chromosomes are composed primarily of RNA, while DNA is only present in mitochondria.
Verified step by step guidance1
Understand that chromosomes and DNA have a structural and functional relationship in eukaryotic cells.
Recall that DNA is a long molecule that carries genetic information, and in eukaryotes, it is organized within the nucleus.
Recognize that chromosomes are not separate molecules but rather structures made up of DNA tightly packaged with proteins, mainly histones, forming chromatin.
Note that this packaging allows the long DNA molecules to fit inside the nucleus and plays a role in gene regulation and chromosome stability.
Eliminate incorrect options by understanding that chromosomes are not membrane-bound organelles, they do not primarily consist of RNA, and DNA is not arranged as many chromosomes linked end-to-end.
