How DNA Controls the Workings of the Cell
Below are two partial sequences of DNA bases (shown for only one strand of DNA) Sequence 1 is
from a human and sequence 2 is from a cow. In both humans and cows, this sequence is part of a
set of instructions for controlling a bodily function. In this case, the sequence contains the gene to
make the protein insulin. Insulin is necessary for the uptake of sugar from the blood. Without insulin,
a person cannot use digested sugars the same way others can, and they have a disease called
diabetes
Instructions: Be sure to use a different color to type your answers so that it is easy to identify your
answer when we go over it
1 Using the DNA sequence, make a complementary RNA strand from both the human and the cow.
Write the RNA directly below the DNA strand (remember to substitute U's for Ts in RNA)
2 Use the codon table in your book to determine what amino acids are assembled to make the
insulin protein in both the cow and the human Write your amino acid chain directly below the RNA
sequence
