Getting
started
You
will need to develop skill in two areas: searching the scientific
literature and bioinformatics. We have constructed this course so
that you will develop skills in both of these areas one piece at
a time but often in tandem. Donna Jacobs and I have constructed
an informative tutorial that will teach you how to locate relevant
information concerning a scientific topic of interest. We have also
constructed a tutorial that will teach you the basics in how to
locate and process relevant information of another sort - biological
information.

Overview of the Grant Exercise
Exercise
1. You will obtain a DNA/protein sequence from GenBank.
You will need to annotate
the sequence.
Exercise 2. You will
locate all the related sequences in Paramecium and create a mini-database. This
will require using a few simple Boolean searching routines in Genbank
(AND). You
will need both the amino acid sequences and the nucleotide sequences. You
will construct an alignment of all the Paramecium PP2B nucleotide
and amino acid sequences (separately).
Exercise 3. Using your
nucleotide alignment, you will identify the introns in each PP2B
gene. These will be annotated in your database files. We will be
constructing a poster to display this data in class over a two
weak period.
Exercise
4. The purpose
of this assignment is to identify homologs and relevant papers
using Entrez. First you will identify related sequences in other
species, especially
,
yeast,
mammals, and other model systems (C. elegans, Drosophila, Protozoa,
and zebra fish). This will require a Blast search of the database
using the amino acid sequence of one of the PP2B sequences from
Paramecium. Using this collection, you will construct a simple
table listing the 20 other sequences from other species you have
found
(Genbank
number),
the
species, and any clues about their function (based upon references
in Genbank file. You will use this analysis to
gain clues as to the function of the Paramecium genes in
assignment 4.
Exercise
5. Identifying
function. You will be asked how you might identify the function
of these PP2B genes in Paramecium. You will start with
what you found in exercise 4 above and then will conduct a focused
search using standard information literacy techniques. Based
on a quick read of the abstracts you have obtained and careful
reading of one PP2B review article, you will write a brief two
page summary of possible functions for PP2B in Paramecium. Donna
Jacobs has prepared a detailed
set of guidelines for how you are to prepare your references.
I expect you to provide references for all written assignments
in this class as described in these guidelines.
Exercise
6. The first draft will be your first attempt at
writing a grant proposal. The hypothesis will be derived
from what you have learned
about Paramecium and from your previous work. The material
you have written in Exercises 4 and 5 should be in the grant.
