Gene-editing tool CRISPR wins the chemistry Nobel - Science News
2020年10月7日 · The tool, a programmable molecular scissors known as CRISPR/Cas9, has been used by bacteria and archaea for millions to billions of years to fight viruses (SN: 4/5/17).
A treasure trove of molecular scissors | Science - AAAS
2021年9月30日 · Altogether, the IscB and TnpB protein families represent a giant collection of programmable enzymes that can be harnessed for gene editing. Their diversity in sequence, protein size, and PAM-like motif requirements should make them an invaluable addition to the molecular toolbox.
Explainer: How CRISPR works - Science News Explores
2017年7月31日 · Scientists are now building their own versions of CRISPR RNAs. These lab-made RNAs guide the enzyme to cut specific genes in other organisms. Scientists use them, like a genetic scissors, to edit — or alter — specific genes so that they can then study how the gene works, repair damage to broken genes, insert new genes or disable harmful ones.
The Genesis of CRISPR’s Molecular Scissors
2023年9月27日 · Within bacteria, CRISPR-Cas9 plays a crucial role in protecting cells from viral infections. Using the help of a guide RNA, these molecular scissors first recognize the DNA of invading viruses and then slice apart the viral genome.
Molecular Scissors | Science Project
Ever used a pair of molecular scissors? Restriction enzymes are molecular scissors that cut DNA into pieces. Find out which enzymes will cut, and where by making a restriction map.
Restriction Endonucleases - The Molecular Scissors
Restriction enzymes are also called "molecular scissors" as they cleave DNA at or near specific recognition sequences known as restriction sites. These enzymes make one incision on each of the two strands of DNA and are also called restriction endonucleases. 4
Sharpening the Molecular Scissors: Advances in Gene-Editing …
2020年1月1日 · Genetics; Techniques in Genetics; Molecular Biology Introduction In recent years, various platforms for genetically engineering somatic and pluripotent stem cells have been developed.
How molecular scissors cut in the right place - ScienceDaily
2017年9月28日 · A research group at Uppsala University has found out how CRISPR-Cas9 -- also known as 'molecular scissors' -- can search the genome for a specific DNA sequence.
Using a molecular scissors to improve CAR-T cell therapy
2024年9月12日 · CRISPR was a key tool in singling out the overabundance of the IL-4 protein in dysfunctional CAR-T cells. CRISPR acts as "molecular scissors" to precisely cut and alter a person's genes.
