After opening the sequence…. What questions do you start with? Is the sequence of good quality? Do you see a poly AAA tail? What does that mean? Where is the start of the cDNA insert?

a. b c d e

a. b c d e

c d e b

What country was this sequence published? A. Russia B. China C. US D. Japan E. France

Blast N: est remember from other cDNA clones! Blast N: nr/nt Blast N: est remember from other cDNA clones! Blast est

BlastX

BLAST X

BLAST X What reading frame is the BLAST X in? Note the alignment! Where does our query start to match? What reading frame is the BLAST X in? A. 0 B. +1 C. +2 D. +3 E. at the Met

Looking at the accession number record: The blast X shows that our query does NOT match to the beginning of this protein…what

a. b. c. Which is the correct reading frame?

Blast P with the ENTIRE ORF

Things go off the track at this point!

Using the information in the Blast P, what does your protein most likely code for? Cytochrome C NADH dehydrogenase Acetylcholinesterase A transcription factor Both B and C
