Question
Write the important structural between DNA and RNA.

Answer

The structural differences between DNA and RNA are as follows :
(i) DNA is found in the chromsomes (located in the nucleus of the cell), whereas RNA is mainly found in the cytoplasm.
(ii) DNA contains $\beta$-D-deoxyribose sugar whereas RNA contains $\beta$-D-ribose sugar.
(iii) Pyrimidine base, thymine is present only in DNA whereas uracil is present only in RNA.
(iv) DNA has a double strand helix structure whereas RNA has a single helical structure.
Functional difference between DNA and RNA : DNA has the property of self-replication and it is the chemical basis of heredity, while RNA controls protein synthesis.
