The process of creating mRNA from
DNA is known as transcription. Using the mRNA to then create a
protein is called translation. We will be practicing both of these
steps of the central dogma using small proteins. Remember
that when mRNA is formed, it complements DNA. C&G are always
paired; however, RNA uses the base U instead of T, so that will be
paired with A in the mRNA strand. DNA and RNA are always read in
the 5’ to 3’ direction, and complementary strands will be
anti-parallel. A table of RNA to amino acids has been included.

Angiotensin II is an 8 amino acid
(aa) peptide that works to help increase blood pressure when there
is low blood volume. It is produced from a much larger, inactive
peptide by activating a restriction enzyme that cleaves off the 8
aa sequence.

Angiotensin II: 8 a.a. ->
Asp-Arg-Val-Tyr-Ile-His-Pro-Phe

1.Using the table above, give a
possible mRNA sequence that would code for this peptide.

(2pt)

2.Explain why the sequence you wrote
above is not the only mRNA sequence that could code for angiotensin
II. (2pt)
