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.
No errors.

No problem! Here are the steps to understanding the information you provided:
1) The DNA molecule has a string of nucleotides in the order CCGCAG.
2) Reading three nucleotides at a time, CCG represents the amino acid glycine.
3) CAG represents the amino acid valine.
4) Therefore, this specific portion of the DNA molecule instructs the cell to join a molecule of glycine to a molecule of valine during protein synthesis.
Based on the information you provided, you mentioned that in a DNA molecule, a specific sequence of nucleotides corresponds to certain amino acids. In this case, the sequence CCGCAG translates to the amino acids glycine (CCG) and valine (CAG).
To understand how this works, let's break it down step by step:
1) Start with the DNA sequence: CCGCAG.
2) Group the nucleotides into sets of three: CCG / CAG.
3) Now, refer to a genetic code chart (also known as a codon table) which maps each three-letter nucleotide sequence to a specific amino acid.
4) Look up the codons CCG and CAG on the chart to find their corresponding amino acids.
5) According to your information, CCG corresponds to the amino acid glycine, and CAG corresponds to the amino acid valine.
6) These two amino acids, glycine and valine, will be combined together to form a protein as instructed by this specific part of the DNA molecule.
In summary, by decoding the DNA sequence and referring to a codon table, we can determine the amino acids represented by specific sequences of nucleotides. This information then guides the cell in building proteins, with each amino acid playing a specific role in the protein's structure and function.
