**Category:** Genetics  
**Subtype:** Nucleotide Composition and Base Pairing  
**Problem Description:** This problem involves analyzing the nucleotide composition of a gene based on given percentages of different nucleotides (A, T, G, and X) and determining the validity of several statements regarding the composition and relationships of these nucleotides.

**Key Points to Consider:**
1. The total number of nucleotides in the gene is 1200.
2. The problem provides specific percentage relationships between the nucleotides A, T, G, and X.
3. The task is to evaluate the correctness of four statements related to the nucleotide composition and hydrogen bonds in the gene.
