RNA as the Genetic Material
(i) Ribonucleic Acid (RNA) was the first genetic material to be discovered.
(ii) RNA used to act as genetic material as well as a catalyst. The 2*-OH group of ribonucleotides is a reactive group that makes RNA acts as a catalyst.
(iii) It is evident that essential life processes such as metabolism, translation and splicing, etc., evolved around RNA.
(iv) The nitrogenous bases in RNA are of two types
Purines Adenine and Guanine
Pyrimidines Cytosine and Uracil
Ribose sugar + Nitrogenous base
Ribonucleostde Ribonucleoside + Phosphate group
