What This Document Is
This document is a detailed exploration of sequence alignment techniques, a core component of phylogenetic reconstruction. It’s designed to provide a comprehensive understanding of the methods used to compare biological sequences – like DNA or proteins – to identify similarities and differences. The material delves into both the theoretical foundations and practical applications of these alignment strategies within a phylogenetic context. It’s part of the MCB 372 course at the University of Connecticut, focusing on the principles behind building evolutionary relationships.
