How a bacterial cell recognizes its own DNA Date: April 13, 2015 Source: Weizmann Institute of Science Summary: It may come as a bit of a surprise to learn that bacteria have an immune system ...
Phages inject their DNA into the bacterial cell, multiply to large numbers using the resources of the host, and then burst out to infect more bacteria in the vicinity. Essentially, they are a ...
Once the DNA pieces were in the cells, the researchers relied on the gene editing system known as CRISPR to grab the free-floating pixel codes and insert them into the bacteria’s genome.
Once the researchers got the bases inside the bacterial cell, it was largely a matter of synthesizing some DNA that included the synthetic bases and putting that in the bacteria as well. The ...
Bacterial cells can "remember" brief, temporary changes to their bodies and immediate surroundings, a new Northwestern University and University of Texas-Southwestern study has found.
In bacterial cells, DNA polymerase III is known to make about 2,000 of these mistakes every time it copies a cell’s genetic material. To maintain genome integrity, the bulk of misplaced ...
He and a colleague proved a theory advanced by the Nobel Prize winners James Watson and Francis Crick, who discovered DNA’s ...
Preserving its DNA ought to be a cell’s top priority. But bacteria slow their DNA repair to a crawl in favor of proofreading gene transcripts. Evolution is a game of trade-offs. Every trait an ...
Now researchers at Indiana University have peeked into that tiny world, producing the first direct images of bacteria extending "harpoons" to snare and absorb bits of DNA. One of the main ways ...
Phosphorus is fundamental to the chemistry of DNA, but a bacterial strain has ... The cells ended up containing 0.19 percent arsenic by dry weight compared to just 0.001 percent in the control cells.
A new study adds to an emerging, radically new picture of how bacterial cells continually repair faulty sections of their DNA. Published online May 16 in the journal Cell, the report describes the ...
