Which of the following is not a basis of difference between plasmid and chromosomal DNA?
a. Presence of histones
b. Nature of histones
c. Nature of nucleotides
d. Linear form of genetic material
a. Presence of histones
b. Nature of histones
c. Nature of nucleotides
d. Linear form of genetic material
View answer and explanation
Correct option: A
