The Urban Barcode Project is a science competition in New York City. A DNA barcode is a DNA sequence that uniquely identifies each species of living thing. In the Urban Barcode Project, student research teams use DNA barcoding to explore biodiversity in New York City. TeaBOL is a DNA barcoding project undertaken by students at the Trinity School.

DNA polymerase (blue) makes many copies of DNA (red) in a cycle of the polymerase chain reaction (PCR).
The DNA sequencing method developed by Fred Sanger forms the basis of automated "cycle" sequencing reactions today.
The cycles of the polymerase chain reaction (PCR).
Kary Mullis explains how the polymerase chain reaction (PCR) was named.
Image of Kary Mullis. In 1985, Kary Mullis invented the polymerase chain reaction (PCR), a method of amplifying or producing many copies of a specific piece of DNA. The revelation came to this eccentric character on a drive in northern California.
Kary Mullis talks about his discovery of the polymerase chain reaction (PCR), a process that allows chemists to produce many copies of a specific fragment of DNA.
The quartz wafer is in the holding position on the DNA synthesizer. The wafer is moved to a vertical reaction vessel for the process of DNA chain elongation.
James Watson describes sequencing the human genome using markers and BACs, and Craig Venter explains using cDNA libraries, ESTs, and shotgun sequencing.
Fred Sanger outlines DNA sequencing.
Kary Mullis speaks about the process of find a specific fragment of DNA amongst many pieces in a complex mixture.
