Proteins are linear polymers of amino acids, They fold into compact structures Sometimes these folded structures associate to form homo or hetero dimers Which one of the following refers to this associated form ?
Correct answer: D. Quaternary structure
- A. Denatured state
- B. Molecular aggregation
- C. Precipitation
- D. Quaternary structure
Explanation
Quaternary structure describes the association of two or more folded protein subunits, which may be identical or different. Denaturation, aggregation, and precipitation describe altered or insoluble protein states rather than the normal level of organisation itself.
