Answer
This statement is false. It's true that the cDNA will "tell" the protein sequence, but the sequence of a protein alone cannot tell its shape. Protein shape/conformation is something that has to be experimentally determined, and this is important because conformation is the source of interaction and function. We will have some idea of conformation based on the sequence (certain motifs can be given away & hydrophobic residues tend to end up in the structural interior).
