Four different PCR reaction mixtures are prepared, each containing a certain percentage of dideoxynucleoside triphosphate (dd NTP) analogs to one of the four nucleotides (ATP, CTP, GTP or TTP).

Synthesis of the new DNA strand continues until one of these analogs is incorporated, at which time the strand is prematurely truncated.

In the late 1970's, two DNA sequencing techniques for longer DNA molecules were invented.

These were the Sanger (or dideoxy) method and the Maxam-Gilbert (chemical cleavage) method.

However, next, the four reaction mixtures are then combined and applied to a single lane of a gel.

The color of each fragment is detected using a laser beam and the information is collected by a computer which generates chromatograms showing peaks for each color, from which the template DNA sequence can be determined.

This technique is based on chain termination by dideoxynucleotides during PCR elongation reactions.

In the Sanger method, the DNA strand to be analyzed is used as a template and DNA polymerase is used, in a PCR reaction, to generate complimentary strands using primers.Our database now contains billions of documents of internet data collected over more than a decade.Enter an IP address or hostname in the field above, and click "GO" to look up technical information."I'm obviously not someone to shy away from something and we've got nine more weeks, hopefully!March 2010 - July 2010Rumors ran wild during the 2010 season of "Dancing with the Stars" when sportscaster Erin Andrews and pro Maksim Chmerkovskiy were paired together.From the resulting page you can navigate further between the different tabs.
