Sentence examples for plasmids from inspiring English sources

Whether using physical maps or the whole genome shotgun sequencing approach, the sequencing exercise involved randomly fragmenting either cloned (copied) or native genomic DNA into very short segments that could then be inserted into bacterial cells as plasmids for amplification, producing many copies of the segments, prior to nucleic acid purification and sequence analysis.

Many plasmids are readily transmitted from one cell to another.

Plasmids have been used extensively in recombinant DNA technology to study gene expression.

Many prokaryotes also contain additional circular DNA molecules called plasmids, with additional dispensable cell functions, such as encoding proteins to inactivate antibiotics.

In addition, some bacteria and archaea have smaller circular DNA molecules called plasmids that typically contain only a few genes.

Because many of the plasmids carrying antibiotic-resistant genes can be transferred between different species of bacteria, widespread resistance to a specific antibiotic can develop rapidly.

Each well will contain a single gene (or, rather, lots of copies of the same human gene) spliced into the genetic material of a "plasmid"—a small, circular DNA molecule.

This is where the automation comes in.The technology for moving a gene from one plasmid to another is not particularly new, but until now the process has had to be tailored individually to each gene.

As long as the receiving plasmid has a pair of DNA sequences that complement those flanking the genes, the genes will rapidly transfer themselves from one plasmid to another all in a single step.Dr LaBaer plans to use this technique to shuttle thousands of genes about simultaneously.

It relies on cutting the DNA that flanks a gene with a special "restriction" enzyme that recognises particular, short DNA sequences as places to make the cut, and then cutting the receiving plasmid at the place where the gene is to be inserted into it.

To make use of a particular gene, however, it needs to be extracted from its storage plasmid and put into a "production-ready" plasmid for insertion into a cell where it can be turned on and induced to produce its protein.
