Some genes specify the production of proteins, while others specify the production of RNA. In either case, It sometimes occurs that one copy of a gene, even being transcribed as quickly as the RNA polymerase molecules can work, cannot produce enough of...

PCR (polymerase chain reaction) is a technique in which cycles of denaturation, annealing with primer, and extension with DNA polymerase, are used to amplify the number of copies of a target DNA sequence by more than 106 times in a few hours. American...

Is primarily laboratory-based technique in which multiple copies of a fragment of DEOXYRIBONUCLEIC ACID (DNA) are produced by a process known as amplification. In essence double-stranded DNA is heated to break down the hydrogen bonding to produce...

The polymerase chain reaction (PCR) is a technique widely used in molecular biology. It derives its name from one of its key components, a DNA polymerase used to amplify (i.e., replicate) a piece of DNA by in vitro enzymatic replication. As PCR...

The wonderland known as Yellowstone National Park has yielded a new marvel _ an unusual bacterium that converts light to energy.The discovery was made in a hot spring at the park where colorful mats of microbes drift in the warmth."This thing was just bizarre," David...
