10. What is the goal of transcription? The goal of transcription is to build a strand of mRNA from
the complementary DNA template strand.
11. Where does transcription occur within the cell? Transcription occurs within the nucleus of
the cell.
12. What is the goal of translation? The goal of translation is to build a protein.
13. Where does translation occur within the cell? Translation occurs in the cytoplasm of the
cell.
14. Amino acids are put together by peptide bonds and form a(n) protein.
15. What strand do you look at in order to write down your amino acid sequence? In order to
write down the amino acid sequence, you look at the mRNA strand to get the codons which
code for the amino acids that build the protein.

20. What would happen to the protein above if the sequence of DNA changed by one base?
Provide an example of how the protein would change using the above strand.
Answers will vary here. If the amino acid sequence above changed by one base pair, the entire
protein could change. For example, if a base was substituted for another base, it could change
the amino acid sequence, changing the protein formed. If a base was added or deleted, there
would be a shift in the sequence, and the majority of the sequence would change, changing the
protein dramatically. Also, there is a chance nothing would change with the protein. For
example, if AUU changed to AUC, it codes for the same exact amino acid and the protein would
not change.
