Following are the difference between DNA and RNA.
DNA
|
RNA
|
|
1.
|
DNA mean Deoxyribonucleic acid
|
RNA mean Ribonucleic Acid
|
2.
|
DNA composed of two chains that coil around each other to form double helix.
|
RNA usually is a single-strand helix contains short chains of nucleotides
|
3.
|
DNA is self replicates.
|
RNA synthesize from the DNA
|
4.
|
DNA found in nucleus, also very less amount present in mitochondria.
|
RNA found in cell’s nucleus, its cytoplasm, and its ribosome.
|
5.
|
Quantity of DNA in cell is fixed
|
Quantity of DNA in cell is not fixed. It is variable.
|
6.
|
The bases present in DNA are adenine, guanine, cytosine and thymine.
Where adenine pair with Thymine
|
The bases present in RNA are adenine, guanine, cytosine and Uracil.
Where adenine pair with Uracil.
|
7.
|
Only one type of DNA is present in body.
|
Mainly Three different types of RNA: m-RNA, t-RNA and r-RNA.
|
8.
|
DNA is a much longer polymer than RNA
|
RNA molecules are variable in length , but much shorter than long DNA polymer.
|
9.
|
DNA transmission of genetic information to make other cells and new organism
|
RNA have function own their types. RNA used to transfer the genetic code from the nucleus to the ribosomes to make proteins.
