DNA vs RNA

 DNA and RNA both contain nitrogenous bases, but they have a key difference in one of their bases.

Nitrogenous Bases in DNA:

1. Adenine (A)
2. Thymine (T)
3. Cytosine (C)
4. Guanine (G)

Nitrogenous Bases in RNA:

1. Adenine (A)
2. Uracil (U) (instead of Thymine)
3. Cytosine (C)
4. Guanine (G)

Key Difference:

• DNA contains Thymine (T), while
• RNA contains Uracil (U) instead of Thymine (T).

This substitution helps distinguish RNA from DNA and affects RNA’s structure and function.
