Differentiate DNA and RNA

Explanation

(i) DNA and RNA both have four bases (two purines and two pyrimidine)
(ii) Adenine (A) and Guanine (G) are the purines.
(iii) Cytosine (.C.) , Thymine (T) and uracil (U) are the pyramidines.
(iv) In DNA molecule , Adenine (A) , Guanine (G) , Thymine (T) and Cytosine are present.
(v) In RNA molecule , instead of Thymine (T) , Uracil (U) is present.
(vi) Therefore , the nitrogeneous base Thyminen is unique for DNA , while uracil is unique for RNA .
