Comparing DNA Sequences

Mr. Anderson explains how DNA sequencing has revolutionized biology by allowing us to compare DNA sequences and understand evolutionary relationships. He introduces cladograms as a way to visualize these relationships and provides an exercise to compare DNA sequences. The video also includes a tutorial on using NCBI and BLAST to search for and compare DNA sequences, demonstrating how to find evolutionary significance through these tools.
