14.24 Write the important structural and functional differences between DNA and RNA.
Structural differences between DNA and RNA:-
(i) The sugar moiety in DNA is D-2-deoxyribose whereas sugar moiety in RNA is D-ribose.
(ii) DNA contains thymine but it is absent in RNA.
(iii) The helical structure of DNA is double-stranded whereas it is single-stranded in case of RNA.
Functional differences between DNA and RNA:- The main function of DNA is to provide heredity but the main function of RNA is a synthesis of protein in a cell.
