NUCLEIC ACIDS:: PART 3

Pentose sugar

-          It is present in both nucleic acids in two different forms.

-          The two nucleic acids are distinguished primarily on the basis of 5-carbon keto sugar or called ribose.

                                                     

-          DNA has 2-deoxyribose nucleic acid and RNA has ribose nucleic acid.

                               

-          Ribose reacts with orcinol in HCl solution containing FeCl whereas deoxyribose diphenylamine in acidic solution.

-          Compounds containing only nitrogenous bases and pentose sugars are called nucleosides.

-          Nucleotides contain pentose sugar, nitrogenous base and phosphate group.
