Bioinformatics
Def.: where the rubber meets the road (i.e., where computer science meets biology)
"The mathematical, statistical and computing methods that aim to solve biological problems using DNA and amino acid sequences and related information.”
Central Dogma: DNA -----> RNA -----> protein
? What is a genome ?
Total amount of the DNA found within one complete set of chromosomes
M. Cummings, 2000
? How much DNA is in the human
genome ?
3 billion base pairs of DNA
?Size of the Human Genome?
GenBank has over 30 billion bases and is doubling every year
How do we access and analyze the data?
?What are the challenges?
10 sets of encyclopedias, 32 volumes each, but only 4 letters: ATGC
Background Info on the HGP
Begun in 1990
15 year project
Background Info on the HGP
Federal and private funding
Multinational project
DOE and NIH at an estimated cost of $3 billion.
Purposes of HGP
