Here, you can see some cDNA and amino acid sequences of the protein myosin in five organisms. Five organisms were chosen to represent a wide range of evolutionary lines so that amino acid and cDNA sequences can be compared for differences and similarities. Although all five of these organisms have myosin, the nucleotides encoding the production of this protein have diverged over evolutionary time.


Yeast: Saccharomyces cerevisiae

Chicken: Gallus gallus

Mouse: Mus musculus
