The eukaryotic genome differs from the prokaryotic genome because:
Correct answer: B. The DNA is circular and single stranded in prokaryotes
- A. The DNA is complexed with histone in prokaryotes
- B. The DNA is circular and single stranded in prokaryotes
- C. Repetitive sequences are present in eukaryotes
- D. Genes in the former case are organized into operons.
Explanation
(b) : Genome refers to the total sets of chromosomes carried by each cell of the organism. In prokaryotes the genetic material is circular and single stranded DNA. It has no association of histones. The eukaryotic genetic material is linear and double stranded DNA. It is associated with histone proteins to form nucleosome unit.

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.
