Chromosomes are Composed of DNA And

Question

Chromosomes are composed of DNA and
A)RNA.
B)alleles.
C)lipids.
D)proteins.

Accepted Answer

Chromosomes are made up of DNA and proteins, which together form a tightly coiled structure called chromatin. The proteins help to organize and compact the DNA, and also play a role in regulating gene expression. While RNA is involved in the process of gene expression, it is not a major component of chromosomes themselves. Alleles are different versions of a gene that can exist at a particular location on a chromosome, but they are not themselves physical structures within the chromosome. Lipids are not typically found within chromosomes, and do not play a direct role in their structure or function.
