Not exact matches

These elements insert themselves into the host genome using two enzymes that they encode for themselves: an endonuclease that cleaves the host chromosome in a specified location, and a reverse transcriptase that copies the retrotransposon's DNA back into the host genome.

Those genes make endonucleases — DNA - cutting enzymes that target one spot in an organism's entire genetic catalog, or genome.

Next, a copy of the homing endonuclease gene with its surrounding DNA inserts itself into the gap as the cell heals the breach.

It covers any endonucleases that target more than a dozen DNA bases and consist of two molecular components that do not occur naturally together, Choulika says.

Our study reveals a family of endonucleases that use dual - RNAs for site - specific DNA cleavage and highlights the potential to exploit the system for RNA - programmable genome editing.

Through the combination of CRISPRs and RNA - guided endonucleases, such as Cas9, («Cas» stands for CRISPR - associated), bacteria are able to utilize small customized crRNA molecules (for CRISPR RNA) to guide the targeting and degradation of matching DNA sequences in invading viruses and plasmids to prevent them from replicating.

(A) A CXCR4 - specific ZFN pair was generated, comprised of two DNA - binding zinc finger proteins (ZFPs) each fused with a FokI endonuclease monomer.

For editing the genome, this system makes use of 3 components, a guide RNA (gRNA) of about 125 nt that specifies the target, the Cas9 endonuclease that creates the DNA double - strand break (DSB) at the target site, and a donor oligonucleotide or plasmid as the repair material if needed (for knock in models).

He cited the example of the Hamilton Smith, who was working in the obscure field of bacterial immunity and discovered restriction endonucleases, which revolutionized DNA modification and earned a Nobel Prize.

Cas9 is the endonuclease enzyme part of CRISPR / Cas9 system that cuts the DNA, while RNA is the CRISPR guide, directing the enzyme to specific sites in the genome so that precise genome edits are possible.

Introduction of DNA double - strand breaks by site - specific endonucleases called meganucleases is being successfully used to target endogenous genes in human cells.

It has recently been described that Xpa is essential to recruit endonucleases and polymerases to the damage sites to restore the original DNA sequence [27].

While native CRISPR / Cas systems have a variety of enzymes responsible for processing foreign DNA as well as the RNA guides required for endonuclease function, when used for genome engineering, the only CRISPR protein required is the Cas9 endonuclease or a variant thereof.

Despite the well - established significance of strand - specific nicking in MMR, the mechanism (s) by which MutS and MutL assemble on mismatch DNA to allow the subsequent activation of MutL's endonuclease activity by β - clamp / PCNA remains elusive.

ERCC1 - XPF is an endonuclease complex required for nucleotide excision repair, interstrand crosslink repair and the repair of a subset of DNA double - strand breaks.
