Given below are two statements: Statement I: A unit formed by the attachment of a base to 1' position of sugar is known as a nucleoside. Statement II: When nucleoside is linked to a phosphorous acid at 5' position of sugar moiety, we get nucleotide. In the light of the above statements choose the correct answer from the options given below:
Statement I is false but Statement II is true.
Both Statement I and Statement II are true.
Both Statement I and Statement II are false.
Statement I is true but Statement II is false.
Statement I is correct: A nucleoside is formed when a nitrogenous base is attached to the 1' position of a pentose sugar through an N-glycosidic linkage. Statement II is incorrect: A nucleotide is formed when a nucleoside is linked to a phosphoric acid (not phosphorous acid) at the 5' position of the sugar moiety through a phosphoester linkage.
