Phylogenetic trees represent evolutionary history, by showing the course of evolution of species from genomic sequences. These trees can reveal connections between different species as well as characterise new unknown sequences in the tree-of-life. With the decreasing cost of high-throughput sequencing, characterisation of unknown sequences seems to be a popular question. I will present a case study on characterising a single sequence using phylogeny; a step-by-step guide of constructing a phylogenetic tree using software framework for phylogenetic analysis, EPoS. We will cover BLAST , Multiple Sequence Aligment (MSA), reconstruction of consensus trees and comparing the generated tree to the tree-of-life. For your interest, we will also provide supplementary materials which you can visit to learn more techniques and gain a deeper understanding of the underlying theory of tree generation.
