Step-by-Step Analysis
Consider how a nucleotide substitution that changes an amino acid can influence protein structure at different organizational levels. Option: quaternary structure A change in one subunit’s amino acid can alter how that subunit interacts with other subunits in a multimeric protein, potentially affecting the quaternary arrangement and stability. If the altered residue disrupts subunit interfaces or binding affinities, qua......Login to view full explanation
