• The molecule of tRNA bonds with mRNA before it bonds to an amino acid.
• The mRNA code determines which tRNA molecules are used.
• The amino acid chain is brought in at the beginning of the process.

What happens to mRNA after it completes transcription?

• It enters the cytoplasm and moves toward ribosomes.
• It becomes part of the nucleolus.
• It remains in the nucleus.
