Using the template below that represents the four levels of protein structure, place an X on each level that is expected to be altered as a result of the amino acid substitutions shown in Figure 1.
Understand the Problem
The question is asking to identify which levels of protein structure (primary, secondary, tertiary, quaternary) are expected to be altered as a result of certain amino acid substitutions. The answer will involve marking these levels with an X in the provided template.
Answer
Primary, secondary, and tertiary structures are altered.
Amino acid substitutions are expected to alter the primary, secondary, and tertiary structures. The quaternary structure may be affected if the protein has multiple subunits.
Answer for screen readers
Amino acid substitutions are expected to alter the primary, secondary, and tertiary structures. The quaternary structure may be affected if the protein has multiple subunits.
More Information
Amino acid substitutions change the sequence, potentially affecting how the chain folds or interacts, impacting higher structures like secondary and tertiary. Quaternary structure is only affected if the protein functions as a part of a larger complex.
Tips
A common mistake is assuming only primary structure changes. Secondary and tertiary structures are interconnected and can be influenced by even small substitutions.
