Rearrange the following steps of protein synthesis in chronological order. Begin with step one at the top and put the final step on the bottom. = a chain of amino acids is assembled forming a protein
tRNA brings amino acids to the ribosome
= mRNA is transcribed from the DNA in the nucleus
EmRNA leaves the nucleus and goes to the ribosome for translation
