I forgot to add the following statements. Thank you.
1)Say, for example, a bit of a DNA molecule has a string of nucleotides in the order CCGCAG. Reading three “letters” at a time, CCG stands for the amino acid glycine. CAG stands for the amino acid valine.
2) So this piece of the DNA molecule tells the cell to join a molecule of glycine to a molecule of valine when it is making a protein.
