Phylogenetic Trees, Part 1: Pairwise Alignment of Related DNA / Protein Sequences using the LCS Algorithm

This lesson is the 1st in a unit on constructing Phylogenetic Trees from DNA or Protein Sequences. Students build an Excel spreadsheet to model the simplest implementation of the LCS (Longest Common Subsequence) algorithm in order to calculate the degree of homology between 2 sequences.

Inquiry Lab: Identifying Bacteria using Morphology, Physiology, and Molecular Data

Bacteria are prokaryotic organisms that can be found almost anywhere on earth.  Identifying prokaryotic species can be difficult in a high school lab.  The purpose of this lab it to use information that is known about bacteria cell wall composition, size, shape, arrangements, enzymatic activity, colony growth, and molecular data (DNA) to identify species (or group of prokaryotes) of known and Read more about Inquiry Lab: Identifying Bacteria using Morphology, Physiology, and Molecular Data
