Research at UC Berkeley and elsewhere suggests that CRISPR-Cas9 constantly feints with the cell's DNA repair system: as the enzyme cuts at its target site, the cell repairs the DNA, and CRISPR-Cas9 cuts again, repeating this vicious cycle until a mutation arises in the DNA that prevents enzyme binding, at which point the CRISPR-Cas9 molecule moves on to find another binding site.
There seems to be something in her DNA that prevents her from quiet submission.
So they used infrared laser beams to cause the particles to release strands of DNA that prevented clotting and then to release other strands that restored clotting.
Apparently, there is something in Chomsky's DNA that prevents him from discussing Latin America outside the context of U.S. imperialism.
Unfortunately, as Vimeo user Phil Whitehead has pointed out, there's one major flaw in Futurama's DNA that prevents it from really being a show about the future: it's completely reliant on the male gaze.
Being applied for pericentromeric repeats, this method identified the insulator activity of gamma-satellite DNA that prevents heterochromatin spreading beyond the pericentromeric region [ 29].
Insulators are DNA elements that prevent inappropriate interactions between neighboring chromatin domains, and CTCF is a major insulator binding protein in the vertebrates that mediate the insulator activity.
We hypothesised that FFPE samples even after de-crosslinking may still contain DNA crosslinks that prevent specific hybridisation and therefore render the sample useless for aCGH.
Five of the phages did not yield DNA amplicons with any of the primer combinations tested (ϕ1, ϕ4, ϕ7, ϕ12 and ϕ16), either due to gene absence, sequence divergence or DNA modifications that prevent efficient PCR amplification [ 36, 37].
DSBs trigger activation of the DNA damage response pathway and DNA repair occurs through an elaborate mechanism involving DNA damage checkpoints that prevent the cell cycle from proceeding until the lesion is repaired (reviewed in Polo and Jackson 2011).
