Bioinformatics tutorials

This six minute video describes some of the history of bioinformatics.

This five and half minute video introduces some of the basic skills for using Cn3D.

BLAST for beginners introduces students to blastn, a commonly used tool for comparing nucleotide sequences (DNA and RNA).  This popular tutorial shows how to do a blast search with a nucleotide sequence, highlights information in the search results, and shows how to interpret the E value and alignment scores.

DNA barcoding is an important technique for identifying many kinds of animals, insects, and plants.  In this technique, PCR is used to amplify a short (650 base) region of the MT-COI gene from mitochondrial DNA.  The DNA sequence is then determined from the PCR product.  If this sequence has been found before, it can be used to identify the type of organism that contributed the DNA.

Microarray and Next Generation DNA sequencing technologies have given us new abilities to understand how living things respond to environmental change. One of the ways we can use this new information is to study gene expression under different conditions. In this activity, we will explore microarray data from plants as they experience drought.
