A plasmid is a small loop of DNA that contains genetic information to help bacteria perform functions such as making use of unusual food sources, resisting antibiotics meant to prohibit growth, or carrying the genes necessary to transfer DNA from one bacterium to another.

What is a promiscuous plasmids?
plasmids that have transfer systems that allow transfer of DNA to unrelated species are called promiscuous plasmids.
What are the 2 types of DNA plasmids found in microorganisms?
Plasmids are autonomous DNA molecules of varying size which are localized within the cytoplasm of bacteria. There are two kinds:virulence plasmids = determines the virulence factors of the bacteriaresistance plasmids (R-plasmids) = determines the bacteria's resistance to anti-infective agents
When plasmids are used to transfer foreign DNA to other cells the plasmid is called?
When plasmids, are used to transfer foreign DNA to other cells the plasmid is called a
What is inside the bacterium below is a small circular piece of DNA called?
Chromosomes unlike our cell they roam freely in the cytoplasm
Extrachromosomal DNA in prokaryotic cells can be found in the form of?
Plasmids.
What is the function of plasmid DNA?
Plasmids have small pockets of DNA in them.

Small accessory chromosomes found in bacteria and useful in recombinant DNA procedures are called?
plasmids.

Circular DNA molecules that can replicate independently are called?
Circular DNA that can replicate on their own are called plasmids. In the field of biotechnology, plasmids are of great importance. Mitochondria also has some of its own DNA.

What does plasmids do?
plasmids are vectors that are used to replicate recombinant DNA in a host organism or cell. they are normally used in cloning experiments.
What happens after genetically modified plasmids inserted into bacteria?
Plasmids are cloned and start producing protein .
What are the research tools that were used in the past and are use today to study DNA structure and function?
DNA atomic structure - X-ray crystallography DNA base sequencing - Polymerase Chain Reaction in conjunction with gel electrophoresis. DNA function - splicing DNA fragments into plasmids, then infecting host bacteria. Other methods include heredity studies. J Ayres
Extrachromosomal DNA in prokaryotic cells can be found in the form of?
Plasmids.
In bacteria genes occur as what?
plasmids...circular strands of DNA
