Consider the given two statements:
Statement I: A nitrogenous base is linked to the OH of 1'C pentose sugar through a N-glycosidic linkage to form a nucleoside.
Statement II: When a phosphate group is linked to OH of 5'C of a nucleoside through phosphoester linkage, a corresponding nucleotide (or deoxynucleotide depending upon the type of sugar present) is formed.
 
1. Statement I is correct; Statement II is incorrect
2. Statement I is incorrect; Statement II is incorrect
3. Statement I is correct; Statement II is correct
4. Statement I is incorrect; Statement II is correct
