Answer:
False.
Step-by-step explanation:
Two main types of nucleic acid are deoxyribonucleic acid (DNA) and ribo nucleic acid (RNA). DNA is present as the genetic material of most of the organism except some viruses.
DNA is generally a double stranded molecule except in some viruses only. The ribonucleic acid is a single stranded molecule in most of the living organism but some have viruses have double stranded RNA. Hence, ribonucleic acid in general cases is single stranded in nature.
Thus, the correct answer is option (b).
