There are two types of nucleic acid-
(a) deoxyribonucleic acid (DNA)
(b) ribonucleic acid (RNA)
The main difference between these two acids are as below
| DNA | RNA |
| (i) In DNA, deoxyribose sugar is found | (i) In RNA, ribose sugar is found. |
| (ii) DNA contains four bases i.e. adenine, guanine, cytosine and thymine | (ii) RNA contains four bases i.e. adenine, guanine, cytosine and uracil. |
| (iii) It has double strand helix structure. | (iii) It has single strand helix structure. |
