Getting DNA into a living cell sounds simple, until you remember the cell’s outer membrane acts like a guarded wall. DNA ...
Mutations are changes in the molecular "letters" that make up the DNA code, the blueprint for all living cells. Some of these changes can have little effect, but others can lead to diseases, including ...
A new family of enzymes enables precise cuts in single-stranded DNA, offering powerful new tools for genetic engineering and expanding possibilities in biotechnology. (Nanowerk News) A few years ago, ...
New research from a team of genome scientists and DNA damage response experts breaks new ground in understanding the function of a protein currently limited in clinical trials for cancer treatments.
An INRS team discovers a new family of enzymes capable of inducing targeted cuts in single-stranded DNA . A few years ago, the advent of technology known as CRISPR was a major breakthrough in the ...
Despite its utility, PCR’s main limitation is that it requires precise cycles of heating and cooling to amplify DNA. The thermal cyclers that perform this operation are clunky, relatively expensive, ...
When an SSB appears, polymerase epsilon approaches the nick before retracing its steps thanks to its exonuclease, allowing fork reversal to take place. The nick is repaired as an SSB, and replication ...
A rapid isothermal amplification technique enables pathogen identification and antibiotic resistance detection in low-resource settings. Recombinase polymerase amplification (RPA) is a technique for ...
