L10. PROTEINS AND EVOLUTION

1- Introduction

Genes are made of DNA and are inherited from parent to offspring. 
Soma DNA sequences code form RNA which turns 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.  

2-Procedure 

We compare the protein "Cytochrome C":
