1 Using the DNA sequence, make a complimentary RNA strand fromboth the human and the cow. Write the RNA directly below the DNA strand (remember tosubstitu,~ U's for T's in RNA)

2. Use the codon table in your book to determine what eminoacidsareassembled to make theinsulin protein in both the cow and the human. Write your amino acid chain directly below theRNA sequence.

Analysis

1. Comparinq the human gene to the cow gene, how many of the codons are exactly thesame? !i

2. How many of the amino acids in the sequence are exactly the same? ----'G~__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.
