प्लाज्मिड्स इसके अंग्रेजी अर्थ का उदाहरण

In agarose gel electrophoresis, the restriction fragments yield a band pattern characteristic of the original DNA molecule and restriction enzyme used, for example the relatively small DNA molecules of viruses and plasmids can be identified simply by their restriction fragment patterns.

This resistance might be because a type of bacteria has intrinsic resistance to some antibiotics, because of resistance following past exposure to antibiotics, or because resistance may be transmitted from other sources such as plasmids.

This stress-induced unwinding was shown to coincide with DNA promoter regions of bacterial plasmids and may direct the global response of cells to changes in their external environments by affecting which genes are transcribed.

flexneri also has two other small multicopy plasmids, but some strains of S.

flexneri have more plasmids that are suspected to confer antibiotic resistance.

Enterobacter may also develop resistance by acquiring plasmids.

Early cloning experiments may be conducted using natural plasmids such the ColE1 and pSC101.

Each of these plasmids may have its advantages and disadvantages.

Many other plasmids were artificially constructed to create one that would be ideal for cloning purpose, and pBR322 was found to be most versatile by many and was therefore the one most popularly used.

A large number of other plasmids based on pBR322 have since been constructed specifically designed for a wide variety of purposes.

Examples include the pUC series of plasmids.

This sample did not contain any plasmids.

QIAGEN introduced the first kit for purification of plasmids – small ring-shaped DNA molecules in bacterial cells – in 1986, cutting the preparation time for plasmids from between two and three days down to two hours.
