Researcher finds keys to genome integrity Maintaining the stability and the correct sequence of our genetic information is vital to the accurate transmission of our genetic code.
The accurate processing of these roadblocks is paramount to genome integrity. Defects in this process can lead to cancer, genetic problems and premature aging.
Depending on the degree of genome instability these alterations will determine whether a cell survives, goes into a growth-arrest state, or dies.

New CRISPR-Cas9 strategy edits genes 2 ways The CRISPR-Cas9 system has been in the limelight mainly as a revolutionary genome engineering tool used to modify specific gene sequences within the vast sea of an organism
genome engineering and gene regulation, are initiated with a common step: the Cas9 protein is recruited to targeted genes by the so-called matching sequences of"GUIDE RNA"that help Cas9 latch on to specific sequences of DNA in a given genome.
But until now, genome engineering and gene regulation required different variants of the Cas9 protein; while the former task hinges on Cas9's innate DNA-cleaving activity,
the latter has been achieved by engineered Cas9 variants that have had their DNA-cleaving"fangs"removed, but still retain their ability to latch onto a specific genomic target.
