7. DNA’s Instructions for Insulin

8. What is insulin? Why care?
Insulin is necessary for the uptake of sugar from the blood.  Without insulin, a person cannot digest sugars the same way others can; Instead they have a disease called diabetes.
Type 1 diabetes (there are 3 main types) is a result of a genetic error that causes the person’s body to destroy its own insulin. (Autoimmune disorder)
A person with untreated diabetes will suffer from weight loss, fatigue, and ultimately, death.

9. In humans and cows, this sequence is part of a set of instructions for controlling the production of a protein. 
This sequence contains the gene to make the
protein insulin:
Human: DNA:
C C A -T A G- C A C- G T T- A C A- A C G -T G A -A G G -T A A
Cow: DNA:
C C G -T A G -C A T- G T T- A C A- A C G- C G A- A G G -C A C
Genetic screening can allow early detection of
Type 1 diabetes.

11. Procedure:
Using the DNA sequence given in table 1, make a complimentary RNA strand for  the human
Write the RNA directly below the DNA strand (substitute U’s for T’s in RNA).
Repeat step 1 for the cow.  Write the RNA directly below the DNA strand in table 2.
Use the codon table in your book/notes 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
