DNA vs RNA

DNA vs RNA

1.
Dna - Deoxyribonucleic acid
Rna - Ribonucleic acid
2.
Dna - It occurs inside the nucleus of cell and some cell organelles but it plants it is present in mitochondria and plant cell.
Rna - It is found in cytoplasm of the cell but very little is found inside the nucleus.
3.
Dna - It is a double-stranded molecule consisting of a long chain of nucleotides.
Rna - It is single-strand helix having shorter chains of nucleotides.
4.
Dna - It stores and transfers genetic information to generate new cells and organisms.
Rna - It is used to transfer genetic code from nucleus to the ribosomes to make proteins and carries DNA blueprint’s guidelines.
5.
Dna - It has two nucleotide strands consisting of phosphate group, five carbon sugar (stable deoxyribose 2) and four nitrogen bases.
Rna - It is single stranded consisting of phosphate group, five carbon sugar (less stable ribose) and four nitrogen base.
6.
Dna - Nitrogen base pairs are Adenine links to Thymine (A-T) and Cytosine links to Guanine (C-G)
Rna - Here nitrogen base pairs are Adenine links to Uracil (A-U) and Cytosine links to Guanine (C-G).
7.
Dna - DNA is self replicating
Rna - It is synthesised from DNA when needed.
8.
Dna - The DNA helix geometry is in the form of B and can be damaged by exposure of ultra-violet rays.
Rna - The RNA helix geometry is in the form of A. It is more resistant to damage by ultra-violet rays.
9.
Dna - It is a long polymer chain.
Rna - It is shorter polymer.
10.
Dna - DNA produces regular helix i.e. it is a spirally twisted.
Rna - It produces secondary helix or pseudo helix as its stranded may get folded at places.
11.
Dna - It occurs in the form of chromosomes or chromatin fibres.
Rna - It occurs in ribosomes or forms association with ribosomes.
12.
Dna - Quantity of DNA is fixed for cell.
Rna -The quantity of RNA for a cell is variable.
13.
Dna - It is of two types: intra nuclear and extra nuclear.
Rna - It is of four types: m-RNA, t-RNA and r-RNA.
14.
Dna - Life of DNA is long.
Rna - Its life is short. Some RNA’s have very shorter life but some have longer but in all its life is short.
15.
Dna - After melting its renaturation is slow.
Rna - After melting its renaturation is Fast
