2004). Also, whereas bacterial chromosomes are circular, eukaryotic chromosomes are linear. During circular DNA replication, the excised primer is readily replaced by nucleotides, leaving no gap ...

and prokaryotic transcription occurs at a rate of about 40 nucleotides per second (Lewin, 2007), so bacteria must have highly efficient methods of accessing their DNA strands. But how?

The first-of-its-kind in-depth bacterial evolutionary map could pave the way for the development of precision treatments for ...

Certain antibiotic-resistant infections could be treated with precision medicine in the future, thanks to a new resource mapping plasmids the ultimate vehicle of rapid bacterial evolution.

a sort of autonomous genetic element that floats free within a bacterial cell, unattached to the cell’s single chromosome. An episome is a short stretch of DNA, sometimes circular like a small ...

The restriction system destroys invading DNA in bacteria. Blunt ends offer a good way to destroy DNA. However, Mertz found that her EcoRI-cleaved SV40 DNA functioned just like wild-type circular SV40 ...

Bacteria are able to transfer genetic material and, therefore, certain traits via plasmids, which are circular pieces of DNA. Plasmids often carry genes for virulence, survival, or antibiotic ...

Bacteria commonly produce toxins that are ... more than 10,000 bacterial plasmid sequences. Plasmids are small, circular DNA molecules that contain genes, including TA systems.

For generations, a tiny piece of DNA has mastered the art of inheritance by hijacking the yeast cell’s division machinery, ...

“Wild stuff does happen.” The trillions of bacteria in our bodies regularly exchange DNA with each other, but the idea that their genes could end up in human DNA has been very controversial. In 2001, ...
