A ring-shaped, double-stranded, piece ofDNAin bacterial cells that contains genes extra to those in the chromosome. Plasmid genes code for characteristics such as toxin production and the factors that cause antibiotic resistance. Plasmids are convenient vehicles for the introduction of new genes into...
The plasmid is a small, circular, double-stranded,extrachromosomal DNA, capable of independent replication. Their size ranges from 1kbp to several megabasepairs (Mbp), and their number in a singlebacterial cell(copy number) may vary from one to several hundreds. As compared to chromosomal DNA,...
This suggests that DNA adsorbed onto chrysotile is not replicated in vivo. When we searched for substances to release pUC18 adsorbed onto chrysotile, we found that a 300-bp single- or double-stranded segment of DNA releases pUC18 from chrysotile. Competitive adsorption onto chrysotile between ...
A plasmid is defined as a double stranded, circular or linear DNA molecule capable of autonomous replication (Leplae et al., 2004). Many natural plasmids are stably maintained at their characteristic copy number within the growing bacterial population, controlling their concentration and regulating the...
We recently found that a heat-denatured, double-stranded DNA fragment, prepared from plasmid DNA (dsHES), and a sense single-stranded DNA fragment, prepared from single-stranded phagemid DNA (fSense), corrected an inactivated hygromycin-resistance and enhanced green fluorescence protein fusion (Hyg...

Plasmids are small, double stranded, ring-shaped DNA found in vitro, ranging in size from 1-200kb to autonomously replicating in host bacteria. In the host cell plasmid copy number is different, one is the low copy number, each cell contains only one or several plasmid molecules, known as...

Plasmids are most often rings of double-stranded DNA found inside cells but not attached to or associated with the chromosomal DNA. The plasmid carries its own origin of replication, thus it is considered a true replicon. Plasmids are “extra” self-replicating molecules of DNA that are found ...
