Educational Databases for Bioinformatics


This site contains user-friendly tools to launch DNA database searches, statistical analyses, and population modeling from a centralized workspace. Educational databases support investigations of an Alu insertion polymorphism on human chromosome 16 and single nucleotide polymorphisms (SNPs) in the human mitochondrial control region. This site requires Java, Javascript, and cookies - click here to test that you have these features enabled.


Enter DNA sequences, perform multiple sequence alignments, generate phylogentic trees, and search Genbank by BLAST and keywords. Includes mitochondrial reference data from world populations, ancient humans, and other organisms.
Enter data on Alu PV92, test Hardy-Weinberg equilibrium, and compare human populations by contingency chi-square, genetic drift, and genetic distance. Includes PV92 reference data from more than 40 world populations.
Model genetic changes over time to study the effects of drift, selective pressure, and population bottlenecks. The Monte Carlo generator can test 100 or more populations at once and link experiments using different parameters.
