Best Answer

Chromosomes contain hundreds to thousands of genes in one very long strand of DNA. The DNA is coiled around proteins called histones. The DNA seems to form a bigger (of course on a very tiny level) part of the chromosome than the histones. Since DNA is comprised of genes, that means that over half of the chromosome is genes. The exact amount would depend on the chromosome.

What are chromosomes and genes composed of?

Genes are composed of DNA. Chromosomes are composed of DNA and proteins. Genes are the sections of DNA which code for a functional product (such as a protein). Chromosomes are the compact, tightly-coiled form of DNA. These appear before the cell undergoes division/replication.
