A biochemist studies hemoglobin and identifies four levels of structural organization that progressively give the molecule its functional shape. The student is asked to relate each level to its underlying chemical basis, beginning with the level dictated directly by genetic information.
The 4 panels represent levels of protein structure. Which level is established by the SEQUENCE of amino acids encoded by mRNA?
- A
Quaternary (4°)
- B
Secondary (2°)
- Ccheck_circle
Primary (1°)
- D
Tertiary (3°)
Explanation
Primary structure is the linear order of amino acids linked by peptide bonds, directly determined by the codon sequence.
