2b)An ancient gene underwent duplication during the course of evolution to yield two chain genes designated as δ and ε genes. Jessica’s final year project deals with the metagenomic studies of anfH homologous genes from freshwater lake samples in Kampar Eastlake. She successfully cloned and sequenced two partial anfH homologous gene sequences. BlastX analyses revealed that one of the DNA sequences showed highest similarity to AnfH protein from a Brazilian soil bacteria isolate while the second sequence showed highest identity to the AnfH protein sequence of a bacterium that was isolated from Tonle Sap, a freshwater lake in Cambodia. To determine their evolutionary relationship, she subsequently constructed a phylogenetic tree using the corresponding protein sequences. Describe the steps that are required to perform the analysis.
