Most protein coding genes are found in?
Correct answer: C. single copy DNA
- A. repetitive DNA
- B. RNA
- C. single copy DNA
- D. none of these
Explanation
Single copy DNA - because most protein-coding genes are present in the unique (single-copy) regions of the genome, while repetitive DNA mainly serves structural or regulatory functions.

About Chromosomes
Chromosomes are DNA-protein structures that carry genes and become visible during cell division. Coverage includes chromatin, centromeres, sister chromatids, homologous chromosomes, chromosome number, and the distinction between diploid and haploid cells, with links to DNA replication, mitosis and meiosis.
