Q. The eukaryotic genome differs from the prokaryotic genome because
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 organised into operons.
Explanation
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.
