What is RNA,

Chemical structure & composition of DNA, RNA:
nucleoside, nucleotide,4 nitrogenous bases (purine-Adenine, Guanine & pyrimidine bases-cytosine, uracil, Thymine), Pentose Sugar(deoxyribose, Ribose), the phosphate group

Different types of bond
1) between sugar & base:- glycosidic bond
2) between sugar and phosphate:-phosphodiester bond
3) between base &base:-hydrogen bond
4) between 2 nucleotide:-glycosidic bond

Base pairing:-
Adenine pairs with Thymine or uracil with 2 hydrogen bonds
Guanine pairs with cytosine with 3 hydrogen bonds​​
