L10. Proteins and evolution

Introduction: 

Genes are made of DNA and are inherited from parent to offspring. Soma DNA sequences code form RNA which, in turn, codes for the amino acid sequence of proteins. Cytochrome C is a protein involved in using energy in the cell. Cytochrome C is found in most, if not all, known eukaryotes. Over time, random mutations in the DNA sequence occur. As a result, the amino acid sequence of Cytochrome C also changes. Cells without usable Cytochrome C are unlikely to survive. 
Cytochrome C is associated with the inter membrane of the mitochondrion. It is a small protein from eucaryote cell.  

Procedure and conclusions: 
 
We compare the protein "Cytochrome C": 
 
Mamales: horse, whale and donkey
Birds: chicken and penguin
Reptils: snake
Insect: moth
Fungi: yeast
Plant: wheat
