DNA 1. Has two complementary strands. If separated by heating come back when appropriate conditions are provided. 2. Chemically less reactive
3. Structurally more stable, so preferred for storage of genetic material.
4. Genetic material for most organisms.

RNA 1. Is single stranded
2. 2’ – OH group present at every nucleotide – Very reactive 3. Thus, Labile and easily degradable.
4. Genetic material in Virus eg. Tobacco mosaic virus. |
