A plasmid is a small, circular, double-stranded DNA molecule that is distinct from a cell's chromosomal DNA. Plasmids naturally exist in bacterial cells, and they also occur in some eukaryotes.

In this article, we discuss transformation, bacterial transformation in particular, and how scientists can utilize it to ...

"Around half of the bacterial taxa in the wastewater community could pick up the plasmids, giving us a detailed map of horizontal gene transfer events." The study also showed that RAM can be used to ...

Bacteria commonly produce toxins that are lethal to themselves, but also produce the required antitoxins. These toxin-antitoxin (TA) systems may be useful in modifying bacteria for biotechnology ...

For example, every research sample, such as a tube with a DNA plasmid, has two facets: a computer record that contains information ... I realized that a lot of the methods that we’re using, such as ...

KorB acting as a DNA sliding clamp and KorA as a lock which holds KorB in place. Together this complex shuts off gene ...

The system works by regulating the behavior of plasmids, which are small, circular DNA ... However, plasmid copy numbers can fluctuate, causing inconsistent gene expression within bacterial ...

Initially, the agrobacterium cell contains a bacterial chromosome and a Tumor-inducing plasmid (Ti plasmid). The Ti plasmid is removed from the agrobacterium cell, and a restriction enzyme cleaves the ...

The BREX system enhances bacterial antiviral defense by modifying its own DNA to distinguish it from viral DNA, a mechanism more complex than classical restriction-modification systems.

A new DNA sequencing technique that delivers faster and more accurate bacterial infection diagnoses could be implemented nationwide. The method, developed by the Medicines and Healthcare products ...
