DNA stands for deoxyribonucleic acid, while RNA stands for ribonucleic acid.
Both of them carry genetic information; there are lots of differences between
them:
DNA
1. DNA- Deoxyribonucleic Acid; presence of oxygen.
2. Function- Serves as a database of genetic information in higher organisms.
3. DNA is a nucleotide-based double-stranded molecule with a continuous
sequence of nucleotides.
4. Sugars and Bases Composition- Adenine, guanine, cytosine, and thymine
bases have a deoxyribose sugar phosphate backbone.
5. Self- replicating.
6. DNA is fairly stable due to the presence of C-H bonds.
7. Base Pairing between nucleotides:
i. A-T (adenine-thymine) by two hydrogen bonds
ii. G-C (guanine-cytosine) by three hydrogen bonds.
