Taking Transformation to the Next Level With Colony PCR

Transformation is a biotechnology technique that is used daily in research laboratories around the world. This technique allows scientists to force E. coli to take up small, circular pieces of DNA called plasmids from the surrounding environment. Using recombinant DNA technology, these plasmids are engineered to contain genes from different sources.

DNA Sequencing to Save Endangered Species

Since the 1980’s, DNA evidence has been used in the criminal justice system to help convict violent offenders and, just as importantly, exonerate innocent individuals. An approach often used is DNA profiling, a technique where investigators compare the base pair order of DNA found at the crime scene to a suspect’s DNA. Now, another type of genetic analysis – DNA barcoding – is being used to combat illegal wildlife trading.
