5) The following protein (long chain of Amino Acids joined by a Peptide Bond) has been produced. What

would the mRNA and the DNA strands read if the Amino Acids are as follows: (NOTE: there is

more than one correct answer – each of you may choose a different codon for the Amino acid)

AMINO ACIDS PRODUCED

Leucine

Histidine

Lysine

Glutamic

Threonine

Acid

Methionine

Tryptophan

Serine

Cysteine

Valine

(Start)

Aspartic

Phenylalanine

Tyrosine

Glycine

Stop

Acid

6) Using your Amino Acids, mRNA from #5 above:

a. What change (Amino Acids produced) would take place if an “A” was inserted before the first

codon on “a” ? Write down the new Amino Acids from this mutation in the table below.

What type of mutation is this? _________________________________

b. How would the “b” strand change if a “G” was deleted in the second codon? Write the Amino

Acids below:

What type of mutation is this? _________________________________

c. What would the “c” strand read if the fifth base was changed from a “U” to an “A”?

What type of mutation is this? _________________________________
