A. Interacting with regulatory transcription factors
B. Chemical damage and modification by reactive molecules in the cell
✓
C. Forming hydrogen bonds during replication
D. Being recognized by complementary tRNA molecules

📝 Explanation

Enclosing the genetic bases within the hydrophobic core protects the fragile hereditary codes from reactive molecules in the cytoplasm.
