1 Bioinformatics Overview
Bioinformatics is the application of information technology to the management of biological data. Bioinformaticians understand biological problems and computational solutions to produce useful tools.

2 Bioinformatics Outline
Molecular Biology Data Searches Substitution Patterns Phylogenetics Genomics Protein and DNA Structure Prediction Proteomics

3 Bioinformatics Outline
Perl Bioinformatics tools

4 Molecular Biology Genetic material Gene structure Protein structure
Molecular biology tools Genomic information

5 Data Searches Dot plots Alignments Scoring matrices
Dynamic programming Global and local alignments Multiple sequence alignments Database searches

6 Substitution Patterns
Patterns of substitutions with Genes Substitution numbers Variations in Evolutionary rates Molecular clocks

7 Phylogenetics Molecular phylogenetics Phylogenetic trees
Distance matrix methods Maximum likelihood approaches Multiple sequence alignments

8 Phylogenetics Parsimony Inferred ancestral sequences Faster searches
Consensus trees Tree confidence Molecular phylogenies

9 Genomics Prokaryotic genomes Prokaryotic gene structure GC content
Prokaryotic gene density

10 Genomics Eukaryotic gene structure Open reading frames GC content
Gene expression Transposition Eukaryotic gene density

11 Protein and DNA Structure Prediction
Amino acids Polypeptide composition Secondary structure Tertiary and quaternary structure Modeling protein folding Structure prediction

12 Proteomics Protein classification Experimental techniques
