हिन्दीGiven below are two statements :\n Statement I : A unit formed by the attachment of a base to \( 1' \) position of sugar is known as nucleoside\n Statement II : When nucleoside is linked to phosphorous acid at \( 5' \)-position of sugar moiety, we get nucleotide.\nIn the light of the above statements, choose the correct answer from the options given below :
Correct answer · Option 3
Statement I is true but Statement II is false.
Explanation
Nucleoside contains base at \( 1' \) position (Statement I is true). However, nucleotide contains phosphoric acid (\( \text{H}_3\text{PO}_4 \)), not phosphorous acid (\( \text{H}_3\text{PO}_3 \)), making Statement II false.
