Creating Phylogenetic Trees From Dna Sequences How to construct a phylogenetic tree Any DNA RNA or protein sequences can be used to draw a phylogenetic tree But DNA sequences are the most widely used It s pretty cheap and easy now to get DNA sequences Plus DNA contains more information which can make more accurate trees
With DNA sequencing rather than using physical or behavioral features of organisms to build trees we can instead compare the sequences of their orthologous evolutionarily related genes or proteins Creating phylogenetic tree in Genome Workbench from search Please use the sample project to follow this tutorial Create a set of sequences Sequences can be added into Genome Workbench project from search result uploaded from GenBank by accessions or uploaded from FASTA file

A phylogenetic tree can be built by repeatedly identifying both the most dissimilar members and the most similar members in a group of organisms DNA sequences can be used in the study of phylogenetics STUDENT LEARNING TARGETS Use an online software to align DNA sequences and build phylogenetic trees Interpret simple Paul Strode describes the BioInteractive Click Learn activity on DNA sequencing and phylogenetic trees He explains how it teaches students about DNA sequence alignment and how those sequence differences allow researchers to determine relationships between species
