  • Once detected, Cas9 hones in on the site and efficiently cuts the double helix strands. (singularityhub.com)
  • Other companies are interested in sequencing to understand antimicrobial resistance, identify airborne pathogens and bioterror threats, and elucidate the relationship between a gene mutation and disease. (genengnews.com)
  • Scientists have also begun fashioning tiny machine components by coating DNA objects with plastics and other materials. (thebulletin.org)
  • Rather than the first base in a sequence being described as "base 1" as most biologists might think of it, or even "base 0" as computer scientists might, with interbase coordinates the first base is described as the sequence spanning coordinates 0 through 1. (cpan.org)
  • This area of biotechnology research, known as DNA origami, folds DNA into nano-scale shapes designed to perform specific mechanical functions or biological interactions. (thebulletin.org)
  • Combine such machinery with photonic sensors, electric circuits, and complex motion and dynamics, and you are well on your way to a nanorobot made from DNA-a nanorobot that not only mimics mechanical functions but also interacts with biological materials. (thebulletin.org)
  • But the technique, which involves using an enzyme called a nuclease that acts as molecular scissors to "cut" DNA, can cause unintended effects. (scientificamerican.com)
  • Taq DNA Polymerase is a thermostable enzyme derived from the thermophilic bacterium Thermus aquaticus . (sigmaaldrich.com)
  • In experiments used to study non-random chromosome assortment, stem cells are labeled or "pulsed" with a nucleotide analog that is incorporated in the replicated DNA strands. (wikipedia.org)
  • Human glioblastomas are characterized by frequent DNA amplifications most often at chromosome regions 7p11.2 and 12q13-15. (tu-darmstadt.de)
