Exercise 1

In your groups search one of the below sequences using the EMBL nucleotide BLAST and FASTA webservers (http://www.ebi.ac.uk/Tools/similarity.html).

• What is the species distributions and possible function for your sequence?
• What is the function of your sequence?
• Is it related to any other type of RNA?
• Note: if the EBI services are too slow then try BLAST at the NCBI.
