What are the main differences between DNA and RNA

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.
