Bio Molecules
Nucleic Acids
Nucleic acids : DNA, RNA are important factors in heredity complete hydrolysis of DNA yields a pentose sugar, phosphoric acid and N - containing heterocyclic compounds.
DNA → β - D - 2 deoxyribose
RNA → β - D - ribose
DNA → 4 bases : Adenine, thymine, Guanine, Cytosine
RNA → 4 bases : Adenine, Uracil, Guanine, Cytosine.
Nucleoside : A unit formed by attachment of base to 11 position of sugar is called nucleoside
Nucleotide : A unit formed by attachment of phosphoric acid at 51 to nucleoside is called nucleotide
Di nucleotide : 2 nucleotides on adding give a dinucleotide
Nucleic acid :
DNA is the basis of heredity and it gives the genetic information.
