Complete question:
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 digest sugars the same way others can, and they have a disease called diabetes.
1 Using the DNA sequence, make a complimentary RNA strand from both the human and the cow. Write the RNA directly below the DNA strand (remember to substitute U's for T's 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.
Human DNA CCA TAG CAC GTT ACA ACG TGA AGG AAA
Cow DNA CCA TAG CAT GTT ACA ACG CGA AGG GAC
Analysis
1. Compare the DNA Sequence and circle any single base that is different in the cow and human sequences. How many bases are different? _____
2. Examine the amino acids produced. Highlight in yellow any amino acids that are different in the two sequences. How many are there? ______
3. Could two humans (or two cows) have some differences in their DNA sequences for insulin, yet still make the exact same insulin proteins? Explain.
4. Examine the codon chart and list all of the codons that code for the amino acid leucine. List them.
