Which one of the following is wrongly matched A) Adenine, Thymine-Purines B) Thymine, Uracil_Pyrimidines C) Uracil, Cytosine-Pyrimidines D) Guanine, Adenine-Purines
Option A) The sugars which are present in the nucleotide are ribose or deoxyribose. The nitrogenous bases are purines and pyrimidines. The purines are adenine and guanine. The pyrimidines are thymine, uracil, and cytosine. The phosphate is present as phosphoric acid. A purine is attached to pyrimidine by hydrogen bond. Adenine is attached to thymine by two hydrogen bonds while three hydrogen bond is present between guanine and cytosine.
