Question

Which nitrogenous bases are found in RNA?

Hint:

Remember, uracil (U) replaces thymine (T) in RNA, which is a key distinction between RNA and DNA.

Answer 1

Step 1: Understanding RNA.
RNA (Ribonucleic Acid) is a polymer made up of nucleotide units. Each nucleotide contains a nitrogenous base, a sugar molecule, and a phosphate group. The four nitrogenous bases found in RNA are:
1. **Adenine (A)**
2. **Uracil (U)**
3. **Cytosine (C)**
4. **Guanine (G)**
In RNA, uracil replaces thymine, which is found in DNA.

Step 2: Conclusion.
The nitrogenous bases in RNA are Adenine, Uracil, Cytosine, and Guanine.
