When the messenger RNA (mRNA) copy of the code is finally carried out of the nucleus, it leaves through small openings called nuclear pores and enters in the cell’s cytoplasm.
Here the mRNA runs the code through an organelle in the cell called a ribosome. The ribosome will do the translation.
At the ribosome another molecule, called transfer RNA (tRNA), goes to work.
Transfer RNA carries a three base “anticodon” at one end and an amino acid at the other end. The anticodon binds with the matching codon on the mRNA.
In this way tRNA delivers the correct amino acid for the protein being built.
