They are used as DNA delivery units in biotechnology.
It replicates independently of the host chromosome and carries information required for its own replication.
Also carries information that adds extra characteristics to the host cell, those characteristics are usually not vital for the cell.

∙ 15y agoA plasmid is a piece of DNA that has broken off and is capable of replicating without the rest of the DNA string. A plasmid can either be circular or linear. Plasmids are generally found in bacteria and can be injected or may infect it's host. Plasmids are capable of altering the DNA of it's host. This can be helpful in some respects to it's host in that the host (bacteria) may be able to survive it's surroundings.

What is some examples of germs?
your mm
What is the structure of the plasmids?
A plasmid is a double stranded circular DNA
Cells in a cell culture all have the same genetic material because they are A. vectors B. plasmids C. hybrids D. clones?
Cells in a cell culture of similar genetic material are called clones. vectors can be the carriers of viruses . Plasmids are the extrachromosomal genetic material. Hybrids are the cells produced from the combination of two cells.
Is vapor solid liquid or gas?
At room temperature and up to around 100o F, Vaseline is a semi-solid, or quasi-solid, which has characteristics of both a solid and a liquid. It melts at around 100o F, and behaves only as a liquid.
What are visible characteristics?
Visible characteristics are characteristics that are visible. Haha no but they are your outside features.
Bacteria can take up foreign DNA molecules packaged in plasmids?
yes. Some bacteria can take up plasmids present in the solution around them or by getting the plasmid from another bacteria which possess a special "fertility" F-plasmid.
What causes protozoan plasmids?
Protozoa do not have plasmids in nature.
What is a promiscuous plasmids?
plasmids that have transfer systems that allow transfer of DNA to unrelated species are called promiscuous plasmids.
In many bacteria genes that confer resistance to antibiotics are carried on what dissimilation plasmids exons plasmids factors or transposons?
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
Is prokaryote used in plasmids?
No, it's vise versa. Plasmids are used in and by the prokaryotes.
What types of plasmids allows a bacterial cell to kill its competitors?
Bacteriocin Plasmids
Plasmids are unique to what?
Plasmids are small segments of genetic material which are passed from one bacteria to another, so plasmids are unique to bacteria, which may also be referred to as prokaryotes.
What is inside the bacterium below is a small circular piece of DNA called?
Chromosomes unlike our cell they roam freely in the cytoplasm
What is a plasmid and why is it useful to researchers?
Plasmids are important in the phases of bacterial genetics because plasmids are the small circle of DNA for bacteria and is responsible for storing and studying genes. Plasmid is used as the vehicle to genetically engineer bacteria to produce insulin.
How are plasmid classification on their property?
Plasmids are classified as: 1. F plasmid 2. R plasmid 3. Col plasmid F plasmids for fertility factor, it transfers its plasmid to the non fertile making it fertile. R plasmid for certain antibiotic resisitivity..for eg, ampicillin resistance. Col are certain proteins which when produced doesnt let other organisms to invade its cell.
Do mitochondria have plasmids?
No. Plasmids are used for cell replication, and cannot be a fraction of something that a fraction of a cell.
