Just as computer software is rendered in long strings of 0s and 1s, the GENOME or “software” of life is represented by a string of the four nucleotides, A, G, C, and T. To understand the software of either - a computer or a living organism - we must know the order, or sequence, of these informative bits. What is sequencing? Slide: JGI, 2009

A GENOME is all of a living thing’s genetic material. The genetic material is DNA (DeoxyriboNucleic Acid) DNA, a double helical molecule, is made up of four nucleotide “letters”: A-- G-- T-- C-- What is a genome? Slide: JGI, 2009

Coming into the Genome Age For the first time in the history of science students can work with the same data and tools that are used by researchers. Learning by asking and answering question. Students generate new knowledge.

Workshop Objectives Illustrate the evolving concept of “gene.” Conceptualize a “big picture” of complex, dynamic genomes. Guide students to address real problems through modern genome science. Use educational and research interfaces for bioinformatics. Work with “real” genome sequences gathered by students – in the lab or online.

Molecular biology and bioinformatics concepts RepeatMasker Eukaryotic genomes contain large amounts of repetitive DNA. Transposons can be located anywhere; they can mutate like any other DNA. FGenesH Gene Predictor Protein-coding information begins with start, followed by codons, ends in stop. Codons in mRNA (AUG, UAA,…) have sequence equivalents in DNA (ATG, TAA,…). Most eukaryotic introns have “canonical splice sites,” GT---AG (mRNA: GU---AG). Gene prediction programs search for patterns to predict genes and their structure. Different gene prediction programs may predict different genes and/or structures. Multiple Gene Predictors The protein coding sequence of a mRNA is flanked by untranslated regions (UTRs). UTRs hold regulatory information. BLAST Searches Gene or protein homologs share similarities due to common ancestry. Biological evidence is needed to curate gene models predicted by computers. mRNA transcripts and protein sequence data provide “hard” evidence for genes.

What is a gene? Can we define a gene? Has the definition of a gene changed? How can we find genes?

An Evolution of Sorts… Genes as “independent hereditary units (1866), Mendel Genes as “beads on strings” (1926), Morgan One gene, one enzyme (1941), Beadle & Tatum DNA is molecule of heredity (), Avery DNA > RNA > Protein (1953), Crick, Watson, Wilkins Transposons (1940s-50s), McClintock Reverse transcription (1970), Temin & Baltimore Split genes (1977), Roberts & Sharp RNA interference (1998), Fire and Mello
