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.

Chromosome compaction is on the order of several thousand fold ... We developed gel electrophoresis-based assays that could be used to easily score DNA condensation. In these assays, a large nicked ...

A scaleable method for the liquid-phase separation of plasmid DNA from RNA. In the course of experiments on the potential of nucleic acid compaction for enhancement of chromatographic adsorption ...

The diagram illustrates the process of genetic modification using Agrobacterium tumefaciens. Initially, the agrobacterium cell contains a bacterial chromosome and a Tumor-inducing plasmid (Ti plasmid) ...

thermocellum expressed leaf compost cutinase (LCC) via a plasmid for high-temperature PET depolymerization. In this study, the researchers integrated LCC directly into the chromosome of C.
