Complementary DNA is often used in gene cloning or as gene probes or in the creation of a cDNA library.

th: Complementary DNA

# Complementary DNA then binds to the U5 ( non-coding region ) and R region ( a direct repeat found at both ends of the RNA molecule ) of the viral RNA

* Complementary DNA, DNA reverse transcribed from a mature mRNA template

Complementary DNA ( cDNA ) is much more stable than mRNA and so, once the double-stranded DNA has been produced it represents the expressed DNA sequence scientists look for.

* Complementary DNA

DNA ligases have become an indispensable tool in modern molecular biology research for generating recombinant DNA sequences.

Plasmids are now being used to manipulate DNA and may possibly be a tool for curing many diseases.

As a result the first DNA transposon used as a tool for genetic purposes, the Sleeping Beauty transposon system, was a Tc1 / mariner-like transposon that was resurrected from a long evolutionary sleep.

His tool was statistics: long before the molecular model of DNA was introduced by James D. Watson and Francis Crick.

Some inventions and discoveries to come out of Berkeley Lab include: " smart " windows with embedded electrodes that enable window glass to respond to changes in sunlight, synthetic genes for antimalaria and anti-AIDS superdrugs based on breakthroughs in synthetic biology, electronic ballasts for more efficient lighting, Home Energy Saver, the web's first do-it-yourself home energy audit tool, a pocket-sized DNA sampler called the PhyloChip, and the Berkeley Darfur Stove, which uses one-quarter as much firewood as traditional cook stoves.

Because of this and because the mutation rate of animal mtDNA is higher than that of nuclear DNA, mtDNA is a powerful tool for tracking ancestry through females ( matrilineage ) and has been used in this role to track the ancestry of many species back hundreds of generations.

The infectious clone, DNA encoding the genome of a virus, is a standard tool used today in virology.

His inventions include the automated DNA sequencer and an automated tool for synthesizing DNA.

Upon learning the identity of his human DNA donor, Luthor gives Connor a tool ( named Shields ) that unleashes his full Kryptonian powers but also causes him to go into a nearly-blind rage.

* Dialed number analyzer ( DNA ) is a tool used to analyze how dialed strings route

What was then needed was a tool that would cut DNA at specific sites, rather than at random sites along the length of the molecule, so that scientists could cut DNA molecules in a predictable and reproducible way.

While information in cDNA libraries is a powerful and useful tool since gene products are easily identified, the libraries lack information about enhancers, introns, and other regulatory elements found in a genomic DNA library.

Agrobacterium is well known for its ability to transfer DNA between itself and plants, and for this reason it has become an important tool for genetic engineering.

* BLAT ( bioinformatics ), a BLAST-like alignment tool for sequencing mRNA / DNA and protein / DNA

Alkaline phosphatase has become a useful tool in molecular biology laboratories, since DNA normally possesses phosphate groups on the 5 ' end.

In fluorescence microscopy, fluorescence confocal laser scanning microscopy, as well as in molecular biology, FRET is a useful tool to quantify molecular dynamics in biophysics and biochemistry, such as protein-protein interactions, protein – DNA interactions, and protein conformational changes.

DNA occurs in nature as a right-handed double helix and in asymmetric synthesis a chiral catalyst is a valuable tool in the synthesis of chiral molecules from an achiral source.

A DNA database will continue to be compiled as a mission-critical tool in this effort.

According to the NPIA, the database is a successful tool in fighting crime and points out that “ between April 09 and 28th January 2010 the National DNA Database produced 174 matches to murder, 468 to rapes and 27, 168 to other crime scenes .”

In addition, the NPIA says that the “ National DNA Database continues to provide police with the most effective tool for the prevention and detection of crime since the development of fingerprint analysis over 100 years ago.
