Questions that might be answered from a BLAST search
-
How long is the sequence that you used
to search the database?
-
What is the most likely identity of this
sequence? What data supports
this conclusion?
-
What organism is the source of the
sequence? What is the common
name for this organism?
What phylum contains this organism?
What is the accession number for this
sequence?
-
Is this sequence expressed? How do you
know?
If your sequence is expressed, where
(tissue) and when is
it expressed?
Is anything known about factors that
cause your sequence
to be expressed?
-
How many sequences can you find with an
E value less than 0.05?
What organisms did those sequences
come from?
-
Look at the first matching sequence, how
long is the extent of the
alignment and what fraction of the
nucleotides match?
-
Use PubMed to find the possible function
of the protein specified by
your DNA sequence. Describe what's known
about the role of this
protein in the organism that provided the
DNA.
