Q12: The sequence below shows one strand of DNA. Parts of the sequence are in capital letters to
help you identify important features – capitalization does not affect the nucleotide indicated.

a. Underneath that strand write the sequence of the strand of DNA it would be paired with
in a doublestranded helix. Use the single letter code A-adenosine, G-guanosine, T-thymine,
U-uracil and C-cytosine and remember to label the 5' and 3' ends.
b. Next, write the sequence of a possible mRNA transcript of the double stranded DNA
above. Remember that an mRNA must be translatable by a ribosome into a protein. Be sure
to indicate 5' and 3' ends.
c. Translate your mRNA into the appropriate protein. Write the amino acid sequence of the
protein using the single letter amino acid below the mRNA sequence in (b) and label the
amino and carboxy terminals
d. Suppose the underlined, bold a were mutated to be a t. Write the new sequence of your
mRNA transcript below and underneath it the new amino acid sequence of the peptide it
encodes.
e. What kind of mutation would that be?
