, and accessory proteins are natural or artificially created tools for gene editing that are used for developing powerful methods of genetic engineering.
They found out that approximately all archaeal genomes, as well as CRISPR nucleases
, were highly diverse.
Targeted approach to address this challenge was the design of chimeric nucleases
which are complex proteins containing one or two structural units, one of which catalyzes the cleavage of DNA, and the second is capable of selectively binding to specific nucleotide sequences of target molecule, providing the nuclease
action to this site (Table 1) [46, 47].
is reported to be involved in cleavage of complementary strand while Ruvc cleaves the non-complementary strand resulting in the blunt end formation which after re-union gives frame shift mutations or indels 
activity can be quantified by the proportion of digested and undigested PCR products following the formula:
In our study, it was showed that in absence of high quality DNA extraction kit, improvement in detection of FT can be carried out with simple heat inactivation of nuclease
enzymes present in environmental samples or patient serum.

It seems therefore reasonable that for genetic cardiac diseases, the in vivo editing approach involving the direct injection of the nuclease
system might be a better method.

Tandem overproduction and characterisation of the nuclease
domain of colicin E9 and its cognate inhibitor protein Im9.
An additional filter may be attached at the outlet of the water purification system, such as a 0.22 [micro]m screen filter (to retain particles and bacteria) or an ultrafilter (to retain nucleases
and other bacteria by-products) for sequencing work.
This enzyme is a non-specific DNA/RNA nuclease
and belongs to a family of nucleases
denominated PPa-mefinger, a name based on the disposition of the catalytic site, which comprises two beta sheets and an alpha helix (13).
