Nucleic Acids

Step 1: Understanding DNA Base Pairing
- DNA follows Chargaff’s rule, which states that the number of cytosine (C) equals the number of guanine (G), and the number of adenine (A) equals the number of thymine (T).
- Hence, in DNA hydrolysis, cytosine and guanine are produced in equal quantities.
Step 2: RNA Hydrolysis and Base Pairing
- RNA consists of adenine (A), uracil (U), cytosine (C), and guanine (G).
- Unlike DNA, RNA does not follow Chargaff’s rule because it is single-stranded.
- Adenine and uracil are not necessarily in equal amounts in RNA hydrolysis.
Thus, statement I is correct, but statement II is incorrect.
