Sentences with phrase «intact nucleus»

To overcome the problem of visualizing chromatin in an intact nucleus, O'Shea's team screened a number of candidate dyes, eventually finding one that could be precisely manipulated with light to undergo a complex series of chemical reactions that would essentially «paint» the surface of DNA with a metal so that its local structure and 3D polymer organization could be imaged in a living cell.
Making a clone requires an intact nucleus, which would not be available for most extinct species.
They injected intact nuclei from the last living ibex into more than 400 enucleated eggs of the domestic goat.
Cloning may eventually give us basically identical genetic copies of extinct species, but we'll be restricted to animals that went extinct more recently and have well - preserved cells with intact nuclei.
In 2003, Spanish scientists injected intact nuclei from the last living Pyrenean ibex, a wild goat endemic to the French mountain range, into more than 400 enucleated eggs of the domestic goat.
In addition, Erez Lieberman Aiden, the director of the Baylor College of Medicine Center for Genome Architecture, and his colleagues have recently cataloged DNA - DNA contacts in intact nuclei, rather than in DNA that previously had to be extracted from nuclei, a step that adds uncertainty to the data.
He commented: «Mitochondrial and some nuclear DNA fragments have previously been isolated from mammoths frozen in permafrost, but the key question is whether sufficiently intact nuclei could be extracted from mammoth cells, which will have been frozen for at least 10,000 years at relatively high sub-zero temperatures.
