The DNA double helix is composed of two DNA molecules whose sequences are complementary to each other. The stability of the duplex can be fine-tuned in the lab by controlling the amount and location ...

The Polymerase Chain Reaction (PCR) is a technique for the amplification of DNA in vitro (this describes experiments with cells outside their normal environment). PCR amplifies DNA using complementary ...

DNA nanotechnology has become an intense research field, with hundreds of research labs engaged in it, based on the idea that DNA can be used as a programmable structural material for the creation of ...

A team from North Carolina State University and Johns Hopkins University claims to have developed the first DNA-based method that can store, retrieve, calculate, delete and repeatedly overwrite data.

DNA replication is the process by which a cell makes an identical copy of its DNA. This process is performed at the beginning of every cell division so that when the cell divides, each daughter cell ...

DNA methylation is one of the earliest epigenetic modifications to be discovered in human beings. It involves the transfer of methyl (CH 3) groups to the C5 position of cytosine bases that comprise ...

Diagnostic tests for infectious diseases often involve identifying “alien” life – in the form of viral DNA – within a patient. Detecting life on Mars may also rely on DNA detection strategies but, ...

For scientists to access and control inorganic materials' unique properties, they need to be able to control these materials' ...
