In 2012, the research team led by professor Jennifer Doudna (University of California, Berkeley) and professor Emmanuelle Charpentier (Umeå University) were the first people to identify, disclose, and file a patent application for the CRISPR-Cas9 system needed to edit DNA. [20]
The break gets repaired by cellular DNA repair enzymes, creating a small insertion/deletion type mutation in most cases. Targeted DNA repair is possible by providing a donor DNA template that represents the desired change and that is (sometimes) used for double-strand break repair by homologous recombination.
A team of engineers and biologists develop a working WORM computer memory out of salmon DNA molecules by combining the DNA with silver nanoparticles. [114] [115] 7 February Scientists report that rapid declines in some British and European ladybird species are being caused by the spread of the invasive harlequin species. [116] [117]
Up until now, the money Illumina (NAS: ILMN) , Roche, Life Technologies (NAS: LIFE) , and Pacific Biosciences of California (NAS: PACB) have made selling DNA sequencers has come from research labs.

The term modifications in genetics refers to both naturally occurring and engineered changes in DNA. Incidental, or natural mutations occur through errors during replication and repair, either spontaneously or due to environmental stressors. Intentional modifications are done in a laboratory for various purposes, developing hardier seeds and ...
It was widely reported that following an expedition to the ISS, Kelly's DNA underwent a 7 percent change, making him no longer identical to his twin.
