Question
Proteins that fold nascent polypeptides into their functional shape are called A. Heat-shock proteins B. Domain proteins C. Molecular chaperone proteins
Solution
The proteins that fold nascent polypeptides into their functional shape are called C. Molecular chaperone proteins.
Here's a step-by-step explanation:
-
When proteins are synthesized by ribosomes (the protein-making machinery in the cell), they are in a linear form. This is the "nascent polypeptide."
-
However, for a protein to be functional, it needs to fold into a specific three-dimensional shape. This folding process is complex and can sometimes go wrong.
-
To ensure that proteins fold correctly, cells have a type of protein called "molecular chaperones." These chaperones bind to nascent polypeptides and help guide their folding into the correct shape.
-
Therefore, the answer to your question is C. Molecular chaperone proteins.
