BLAST (Basic Local Alignment Search Tool) is a powerful tool for comparing unknown sequences to sequences in online databases. In this part of the tutorial, you will use BLAST to identify and analyze the sequence you assembled in Part B: Go to the BLAST website by clicking the Launch BLAST button. Then follow the instructions below. BLAST Search Instructions 1. In the middle of the page, under the Basic BLAST heading, click nucleotide blast. A new page will appear. 2. Copy the nucleotide sequence shown above, and paste it into the Enter Query Sequence box at the top of the new page. 3. In the Choose Search Set box, select the Others (nr etc.) database. In the pull-down menu directly below it, select Nucleotide collection (nr/nt). 4. In the Program Selection box, select Highly similar sequences (megablast). 5. Click the BLAST button near the lower-left corner of the page. Wait for BLAST to complete the search, which may take 10-30 seconds. A new page displays your search results. The Descriptions section of the page lists similar sequences, or hits, with the best statistical match to your query sequence at the top of the list. You should see sequences from several species. If not, see Hint 1 to determine what went wrong. Based on the BLAST results, what can you conclude about your query sequence?
