Regarding the tertiary structure of a globular protein, the folding pattern is determined by the

A. Repetitive hydrogen bonding along the polypeptide backbone
B. Linear sequence of nucleotides in the corresponding gene
C. Interactions among the variable side chains (R-groups) of the amino acids
✓
D. Condensation of the protein with a carbohydrate moiety

📝 Explanation

Tertiary structure is the overall 3D conformation of a single polypeptide chain, driven by interactions between the R-groups. This includes hydrophobic interactions, ionic bonds, hydrogen bonds, and disulfide bridges. The backbone H-bonding defines secondary structure.

📖 Additional Information

  • Repetitive hydrogen bonding along the polypeptide backbone
  • Linear sequence of nucleotides in the corresponding gene
  • Interactions among the variable side chains (R-groups) of the amino acids
  • Condensation of the protein with a carbohydrate moiety
