A plasmid is a small circular DNA molecule found in bacteria and some other microscopic organisms. Plasmids are physically separate from chromosomal DNA and replicate independently. They typically have a small number of genes — notably, some associated with antibiotic resistance — and can be passed from one cell to another.

When used in a cloning experiment, the vector is initially used with E. coli as the host, up to the stage where the desired recombinant molecule has been constructed by restriction and ligation. The recombinant vector is then purified from E. coli and transferred into S. cerevisiae , usually by mixing the DNA with protoplasts - yeast cells.

The example plasmid on the right has a total size of 7.3kb, including a 1.2 kb insert. The plasmid was digested with 2 unique enzymes (HindIII and BamHI) and run on an agarose gel. The resulting gel image includes a 1kb ladder (lane 1) that has bands ranging from about 500bp to 10kb, with the 3.0kb fragment having increased intensity to serve.

A plasmid is a small, extrachromosomal DNA molecule within a cell that is physically separated from chromosomal DNA and can replicate independently. They are most commonly found as small circular, double-stranded DNA molecules in bacteria; however, plasmids are sometimes present in archaea and eukaryotic organisms.

The T-region of Ti plasmids expresses two genes (No. 1 and 2) in crown-gall cells which are essential for auxin effects. It has been shown that gene 2 (=IaaH) codes for an amidohydrolase which.

Key points: Restriction enzymes are DNA-cutting enzymes. Each enzyme recognizes one or a few target sequences and cuts DNA at or near those sequences. Many restriction enzymes make staggered cuts, producing ends with single-stranded DNA overhangs. However, some produce blunt ends. DNA ligase is a DNA-joining enzyme.

The last discovered plasmid in this study is pAsaXII, found in strain HER1084, isolated from a fish captured in France (Figure Figure6 6). As with pAsaXI, this third plasmid is a derivative of a cryptic plasmid (pAsa2 in this case) and contains a putative mobile insertion cassette (MIC) that interrupts, here again, a TA system.
