 | DNA in the nucleus |
 | One gene unzips |
 | mRNA picks up the code by matching with the DNA nitrogen bases |
 | mRNA carries instructions to the cytoplasm |
 | mRNA arrives at the ribosome |
 | tRNA picks up the amino acids in the cytoplasm |
 | tRNA puts its amino acid in its proper place by matching with the mRNA |
 | amino acids are bonded together to make a protein |
