What must happen to a strand of polypeptides before it becomes a functioning protein?
A. Its introns must be removed.
B. Its amino acids must be activated.
C. It must be folded into its proper shape.
D. A poly-A tail must be placed on its end.
Answer (1)
A strand of polypeptides must be folded into its proper shape to become a functioning protein. This critical step, known as protein folding, determines the protein's functionality. Other processes, such as intron removal or the addition of a poly-A tail, relate to mRNA but not the final protein structure. ;
