Differences between DNA and RNA

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.

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.

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.

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.

9. Complete and instantly reversed.

10. Formed from DNA. Self-replication only in some viruses.
