A scientist studies the formation of the protein glutathione. Arrange the labels to complete the steps for the formation of glutathione. The DNA segment is
replicated using
enzymes.
Amino acids bind to
peptide bonds to
form the protein.
RNA polymerase
initiates transcription
to form mRNA.
The tRNA activates
amino acids to bind
to the peptide bonds.
