Write the important structural and functional differences between DNA and RNA.
The structural differences between DNA and RNA are as follows:
|The sugar moiety in DNA molecules is β-D-2 deoxyribose.||The sugar moiety in RNA molecules is β-D-ribose.|
|DNA contains thymine (T). It does not contain uracil (U).||RNA contains uracil (U). It does not contain thymine (T).|
|The helical structure of DNA is double-stranded||The helical structure of RNA is single-stranded|
The functional differences between DNA and RNA are as follows:-
|DNA is the chemical basis of heredity.||RNA is not responsible for heredity|
|DNA molecules do not synthesise proteins, but transfer coded message for the synthesis of proteins in the cells.||Proteins are synthesised by RNA molecules in the cells.|
