How does genomics differ from genetics?
Genetics looks at single genes, one at a time, as a snapshot.  Genomics is trying to look at all the genes as a dynamic system, over time, to determine how they interact and influence biological pathways, networks and physiology, in a much more global sense. A dynamic process, 2D vs. 3D and 4D. 

Genetics is much more linear than genomics, complicated but not as complex as genomics.  There is a whole lot more we need to understand, some of  which we are only beginning to get glimpses of.  It is exciting, but humbling to realize how much remains to be learned.

Doing (a few of) the numbers: The scale of genomics and bioinformatics

Genomics: a quick tour

Current bioinformatics and chemoinformatics methods of analysis and interpretation are having difficulty keeping up with the rapid growth in sequencing data. New technologies such as microarrays (and advances in existing ones such as mass spectrometry) are leading to rapid growth in new terminology. An even bigger  challenge then new vocabulary is the conceptual shift from classical genetics to a more dynamic genomic “big picture” understanding of genomics, functional genomics, proteomics and structural genomics.

DNA sequences are essentially linear snapshots. In the human genome less than 2 % of  the DNA is genes. To understand genes' functions we need to look at 3D protein structures, and to begin to decipher physiological processes we need to examine changes in gene and protein expression over time (4D).  Our knowledge of genetic variations is still sketchy and crucial to an understanding of the role these differences play in pharmacogenomics.  Will genomic approaches lead to faster drug discovery and development? How can we sort out the incremental advances from the true paradigm shifts without experiencing information overload?

Genome sizes – how many genes?
Oxford English Dictionary quotation in the entry for "genome" Scientific American Oct. 1970 "The human genome consists of perhaps as many as 10 million genes."

Feb. 2001 Science and Nature working drafts t Human genome issues estimated 30K- 40K human genes (much lower than expected), but alternative splicing (in genes) is much higher, producing more variant proteins. Compared to proteins, genes were easy.  Proteomics is the next step.

True microarray story
Bioinformatician/statistician "For statistical significance you should replicate this microarray experiment 100 times. What were you planning on?"
Research biologist: "Once."
Bioinformatician/statistician: "So we compromised on twice." 

informatics:  The world produces between 1 and 2 exabytes of unique information per year, which is roughly 250 megabytes for every man, woman, and child on earth. An exabyte is a billion gigabytes, or 1018 bytes. Printed documents of all kinds comprise only .003% of the total. Magnetic storage is by far the largest medium for storing information and is the most rapidly growing, with shipped hard drive capacity doubling every year. [Lyman, Peter and Hal R.

Economics of genomics
Human genome sequencing
  When the HGP was initiated [1990], vital automation tools and high-throughput sequencing technologies had to be developed or improved. The cost of sequencing a single DNA base was about $10 then; today, sequencing costs have fallen about 100-fold to $.10 to $.20 a base and still are dropping rapidly. [DOE, Human Genome Project and the Private Sector, 2002]  http://www.ornl.gov/hgmis/project/privatesector.html

1990@ $10/base = $3 billion.  2002 @ $.10/base = $3 million 

Nov. 30, 2001 – The Tufts Center for the Study of Drug Development today announced that the average cost to develop a new prescription drug is $802 million. Joseph DiMasi, Center for the Study of Drug Development, Tufts Univ. http://csdd.tufts.edu/NewsEvents/RecentNews.asp?newsid=6 

During the entire decade of the 90s, drugs that accounted for about $17 billion in sales went off patent. The next five years will see drugs with sales of $19 billion lose their patents, according to data from brokerage UBS PaineWebber.  Sam Jaffe "Biotech- Big Pharma Betrothals Declining" Scientist 16 (14): 57 July 8, 2002
