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. Often, the genes carried in ...

Nucleotide sequences of plasmids are usually considered as composed of only four bases. However, because of its bacterial origin, plasmid DNA contains the two modified bases 6-methyladenine and 5 ...

"It's why bacteria evolve so rapidly," Fu said. "Sometimes, plasmids can integrate into genomic DNA, but this happens quite randomly. They might cause difficulty for individual bacterial survival ...

As mentioned, plasmids are double-stranded circular DNA segments. In order to pass through the thin tube that connects the bacteria, one of those circular strands is cut at a certain point by a ...

Bacteria have multiple defence mechanisms they can use to build resistance to antibiotics, one of the major problems facing public health globally. One of these mechanisms involves plasmids, small DNA ...

During the process, known as “conjugation,” one bacterial cell connects directly to another through a tiny tube that allows the transfer of genetic material fragments known as plasmids. Plasmids are ...

DNA is made up of adenine-thymine (AT) bonds and guanine-cytosine (GC) bonds. The frequency of each type of bond differs substantially across bacterial species. A new study uses this quirk of ...

One of the most important medical advancements in the 20 th century was the discovery of antibiotics. The first antibiotic was introduced in 1910 and radically changed modern medicine, according to ...

Bacteria are amongst the simplest of organisms ... additional DNA is found on one or more rings called plasmids. Eukaryotic cell DNA in a nucleus, plasmids are found in a few simple eukaryotic ...

"With this product, we convert our fast, accurate ENFINIA Linear DNA into plasmids as long as 15 kb with unprecedented speed—accelerating our customers’ work and eliminating their reliance on ...
