ADVERTISEMENTS:
The upcoming discussion will update you about the differences between DNA and RNA.
DNA:
1. It is usual genetic material.
2. It is mainly present in the chromosomes of nucleus and outside the nucleus. It is also present in the mitochondria and chloroplasts.
ADVERTISEMENTS:
3. Usually two, rarely one (Virus ɸ X 174)
4. The number of nucleotide may be up to 4.3 million.
5. Deoxyribose
6. Adenine, Guanine, Thymine and Cytosine.
ADVERTISEMENTS:
ADVERTISEMENTS:
7. AT and GC, throughout the length of the molecule.
8. There are mainly five types, viz., A-DNA, B-DNA, C-DNA, D-DNA and Z- DNA.
9. Partially reversed when cooled slowly.
10. Self-replicating.
RNA:
1. It is genetic material only in some viruses.
2. It is formed in the nucleus and is transferred to cytoplasm.
3. Usually one, rarely two (Reo-virus have two strands)
4. The number of nucleotides do not exceed 12,000.
ADVERTISEMENTS:
5. Ribose
6. Adenine, Guanine, Uracil and Cytosine.
7. AU and GC, observed only at the helical region.
8. There are many types: rRNA, tRNA, mRNA, hnRNA, ssRNA, snRNA, etc.
ADVERTISEMENTS:
9. Complete and instantly reversed.
10. Formed from DNA. Self-replication only in some viruses.
