Which describes the correct sequence of steps of protein synthesis? Group of answer choices The DNA strand unzips and a complementary mRNA strand is copied.

Multiple peptide chains create a protein. The RNA strand travels to the ribosome where the DNA strand "reads" it and brings the appropriate amino acids indicated by the RNA strand nucleotide bases.
