At the JGI--or Joint Genome Institute--I had the opportunity to experience one of the largest utilise desoxyribonucleic acid sequencing operations in the world. Basically, I got to see at first hand the machinery and technology involved in the bidding called whole-genome shotgun sequencing, whereby the set egress of fts in an organisms genome is determined. One of the interference guides, before the tour, gave us an lively voice of this process. In this genome-determining-process, deoxyribonucleic acid from the organism to be sequenced is upset up into pieces about 2,000 to 4,000 bases long through a process called shearing. Then, these fragments of deoxyribonucleic acid are inserted into the deoxyribonucleic acid of a bacterium. When grown on an nutrient agar nursing home, only the transformed bacteria with the plasmid deoxyribonucleic acid containing the fragmented desoxyribonucleic acid with genes for ampicillin resistance and the lacZ gene disrupt by the i nserted DNA can grow on the plate and be sportsmanlike. These face cloth colonies are the ones used in the upcoming steps. Basically, the plasmid DNA is taken out of the bacterium; the fragments are replicated and the terminal base of each fragment is starting line with a fluorescent dye. The tagged fragments are loaded into a high-speed capillary cataphoresis machine, and lasers can read the dyes of the bases as they move through the machine. A computer--at the end--solves the puzzle and determines the organisms genome sequence.
While at the JGI, on our tour, we aphorism an electroporation machine, which induces the bacteria to open their pores, c! ause the plasmids to enter into the bacteria. Also, we saw a robotic bacteria picker, which picks specific white bacteria colonies out of the plate. Furthermore, we saw a large form of thermal cyclers and sequencing machines. Overall, the tour was worthwhile because we learned how specialized institutions much(prenominal) as the JGI sequence an organisms DNA and had the...
