उत्तर
DNA:
(i) Contains deoxyribose type of pentose sugar.
(ii) It is double standed.
(iii) It is genetic material in prokaryotes and eukaryotes.
(iv) It helps in inheritance of genetic information.
RNA:
(i) Contains oxyribose type of pentose sugar.
(ii) It is basically single stranded but due to long length it appears folded.
(iii) It is genetic material only in some viruses.
(iv) It helps in inheritance of genetic information in viruses & protein synthesis in prokaryotes & Eukaryotes.
