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.
The complete set of materials consists of:
- The BLAST for beginners tutorial.
- A set of unknown sequences.
- A set of questions for students to answer.
- Instructors may purchase an updated answer key from our TpT store or download a free copy by signing up for a Digital World Biology educator account.
- Learn about our new teachers guide: BLASTing through the Kingdom of Life Teachers Guide
