Jarvis-Patrick cluster algorithm A non-heirarchial clustering method for conformational
analysis of molecules that uses a "nearest neighbor"
approach to look for clusters of conformations that are the
shortest distance away from each other. Java A programming language developed by Sun Microsystems that
allows small programs (applets) to be run on any computer.
Java applets are typically involved when a user clicks on a
hyperlink on a Web page. Jini Java for small appliances. joule Standard unit of energy in the meter-kilogram system. One
joule is the energy delivered in one second by a one-watt
power source. Approximately equal to 0.24 calories. jumping genes transposons junctional diversification The random loss and gain of nucleotides at immunoglobin
V(D)J joining sites. It increases the diversity of V- region
coding sequences created by recombination. jun oncogene produces the Jun protein, a transcriptional regulator
(with a leucine zipper motif) that recognizes AP-1 sites in
DNA. Similar function to fos. junk DNA The fraction of genomic DNA that is devoid of
function.
