Give reason
Nucleotide ratio in RNA is highly variable.

Explanation

### Step-by-Step Solution:

1. **Understanding Nucleotides in RNA**:
- RNA is composed of four types of nucleotides: adenine (A), uracil (U), guanine (G), and cytosine (C). The presence of uracil instead of thymine (which is found in DNA) is a key characteristic of RNA.

2. **Single-Stranded Nature of RNA**:
- Unlike DNA, which is double-stranded and has complementary base pairing (A with T and G with C), RNA is typically single-stranded. This single-stranded structure allows for a variety of configurations and interactions, leading to variability in nucleotide ratios.
