Question

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.
1. DNA is transcribed into mRNA.
2. Amino acids form a chain.
3. The amino acid chain is folded into a protein in the endoplasmic reticulum.
What step did Stella miss in her explanation?
(1 point)
• mRNA is translated into amino acids.
• tRNA delivers the DNA to the ribosome.
• DNA is replicated into two daughter cells.
• Polypeptide chains express gene traits.

Answer 1

mRNA is translated into amino acids.

Explanation: Stella skipped the translation step where ribosomes read mRNA and, with tRNA, assemble amino acids into a polypeptide chain. The other choices are incorrect descriptions of the missing step.
