Review of course prerequisites
Course objectives




Become proficient at using existing bioinformatics
software
Understand the statistics behind bioinformatics
Write an algorithm that answers a specific
bioinformatics problem
Become acquainted with some ethical issues
surrounding the science of the human genome project
Rationale for offering SoCalBSI
Program
1.
2.
3.
Give participants a chance to understand how
popular bioinformatics algorithms operate
(Clustal W, BLAST, BLIMPs).
Give the students the opportunity to create
software that uses concepts from Bioinformatics
history
Give the students an insight into bioinformatics
so they can make an intelligent determination of
how to achieve education and career goals.
Learning Goals of Didactic
Portion of the Program
Introduce software and databases currently used
by bioinformaticists
Introduce the organization of the data. How data
is gathered and how it is annotated.
Introduce statistics of data analysis.
Introduce the concept of dynamic programming
Give the students an opportunity to create an
algorithm that analyzes sequence data
Encourage the student to research a bioinformatics
company and report on its products.

Power point presentation
 In-class Workshop
 References
 Writing assignment

Definition of Bioinformatics
Many definitions at the moment:
Use of computers to catalog and organize
biological information into meaningful entities.
 Conceptualization of biology in terms of
molecules and the application of “informatics”
techniques (from disciplines such as applied
math, computer science and statistics) to
understand and organize the information
associated with these molecules

Bioinformatics is Multidisciplinary

How much of the genome is defined?
Unknown Function
How is Bioinformatics Used?
Bioinformatics is often used to help “focus”
the experiments of the benchtop scientist
Bioinformatics isn’t going to replace
lab work anytime soon
Experimental proof is still the
“Gold Standard”.

Find genetic markers associated

Sequence DNA in close proximity
to the markers
Compare DNA from afflicted
individuals to DNA of normal
individuals (database)
Find abnormality
Predict gene function from
sequence information
What is the approach used to
sequence genomes?
Divide and conquer
 Split the genome into fragments
 Clone into vectors that can accept large
fragments: yeast artificial chromosomes (YAC
Library)
 Landmarks within the genome can be obtained
using Sequence Tagged Sites (STS)
 Sequences of YAC clones are matched with
each other.
 Sequences that overlap form contigs.

Public funding vs. Private
funding
Public-Taxpayers’ money, international
effort.
Private-Companies that invest money hope
to provide access to their information on a
fee basis. Celera also allows some free
information to small research groups.
Both groups have published the sequence of
the human genome.
