Stella described protein synthesis as a process that makes the necessary proteins for the human body to function. She explained the process in the following steps. DNA is transcribed into mRNA. Amino acids form a chain. The amino acid chain is folded into a protein in the endoplasmic reticulum. What step did Stella miss in her explanation? (1 point) Responses mRNA is translated into amino acids. mRNA is translated into amino acids. Polypeptide chains express gene traits. Polypeptide chains express gene traits. tRNA delivers the DNA to the ribosome. tRNA delivers the DNA to the ribosome. DNA is replicated into two daughter cells. DNA is replicated into two daughter cells.
