Alternatively, the repair activity in a cell extract can be measured by incubating it with nucleoids containing specific damage. A celestial object that orbits the sun along an elongated path. DNA repair can be monitored by incubating cells after treatment with damaging agent and measuring the damage remaining at intervals. The articles in our blog examine new words, revised definitions, interesting images from the fifth edition, discussions of usage, and more. A celestial body, observed only in that part of its orbit that is relatively close to the sun, having a head. The sensitivity and specificity of the assay are greatly enhanced if the nucleoids are incubated with bacterial repair endonucleases that recognize specific kinds of damage in the DNA and convert lesions to DNA breaks, increasing the amount of DNA in the comet tail. Definitions of COMET in various dictionaries. The assay has applications in testing novel chemicals for genotoxicity, monitoring environmental contamination with genotoxins, human biomonitoring and molecular epidemiology, and fundamental research in DNA damage and repair. These frozen remnants can offer a sublime astronomical spectacle, sometimes visible to the naked eye.

The likely basis for this is that loops containing a break lose their supercoiling and become free to extend toward the anode. What is a comet made of Comets, these small bodies with impressive hair, are remnants of the solar system. Electrophoresis at high pH results in structures resembling comets, observed by fluorescence microscopy the intensity of the comet tail relative to the head reflects the number of DNA breaks. Cells embedded in agarose on a microscope slide are lysed with detergent and high salt to form nucleoids containing supercoiled loops of DNA linked to the nuclear matrix. comet cometcomet /kmt k-/ noun countable HAan object in space like a bright ball with a long tail, that moves around the Sun Halleys Comet. The comet assay (single-cell gel electrophoresis) is a simple method for measuring deoxyribonucleic acid (DNA) strand breaks in eukaryotic cells. A person that passes through your life repeatedly who is intense and awesome, and when gone you are still in contact with that person in some way but they are not a continuous partner.
