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.

∙ 13y agoA plasmid is a circular kind of DNA that contains genes, but is separate from what we think of as actually being DNA. The amazing thing is that it can incorporate itself into the chromosomes in the cell (transformation), or remain inside of the cell, but either way it can still be replicated and given to daughter cells, or be given to other bacteria cells. When you hear about bacteria becoming immune to so many antibiotics so quickly, scientists are usually referring to plasmids- they are a mutation, usually an immunity to an antibiotic, that can be passed to potentially every bacteria in the colony. They contain useful genes that can help with survival, and can be passed very quickly and easily between bacteria.

Different kinds of bacterial plasmids based on encoded genes (their roles)
- F-plasmids
(fertility factor or sex factors):
Bacterial cells with F plasmids are called F+ cells and acts as donor cells or +strain
during bacterial conjugation. F factors are involved in bacterial conjugation.
- R-plasmids
(resistance plasmids):
These plasmids encode genes that confer bacterium resistance against antibiotics. R plasmids are easily transferred from one strain to another offering antibiotic resistance to
neighboring
cells easily.
- Col-plasmids:
these plasmids carry genes that produce bacterial toxins called colicins.
- Metabolic plasmids
carry genes involved in the production of metabolic enzymes.

Plasmids are important to genetic engineering because they are used as "carriers" of DNA to be inserted into a cell of interest. A plasmid is a piece of circular deoxyribonucleic acid that can replicate itself.
Plasmids are known as 'mRNA Plasmids'. These plasmids can be used in the production of proteins through gene cloning because it is less complex than a chromosome and can be inserted easily into the bacterial genome.

Vector is the "vehicle" where the to be cloned DNA fragment is inserted (passenger).

∙ 14y agoplasmid is a extra nuclear genetic material ,circular in shape, it is very useful as vector,so in recombinant DNA technology it is useful.

What is the function of the Ti plasmid?
what is the function of the plasmid
What is a self-transmissible plasmid?
A plasmid which encodes genes for its own transfer.
What is a synonym for plasmid?
A plasmid is essentially extra-chromosomal self-replicating DNA
Why are plasmid used as vectors vectors?
They are already tailor-made to insert DNA into another organism. Scientists hijack their mechanism and replace the original DNA/RNA with their own.Agrobacterium tumefaciens causes crown galls in some plants, by inserting its DNA into the plant's genome. To make a vector from this plasmid, researchers removed everything that was not essential for this "inserting of DNA" and replaced it with various other genes.
What is a single loop of DNA found in bacteria?
bacterial plasmid/ plasmid ring
Give two reason why plasmid is useful for DNA transfer?
A plasmid is relatively small in length and can be manipulated to have different genes on it.

What is recombinant Plasmid?
A plasmid is a small, circular, double-stranded DNA molecule that is distinct from a cell's chromosomal DNA. ... Researchers can insert DNA fragments or genes into a plasmid vector, creating a so-called recombinant plasmid. This plasmid can be introduced into a bacterium by way of the process called transformation.
What must researchers know before they begin the process of gentic engineering?
you need to know which restriction enzyme to use. also, who is the doner and the plasmid.
What is plasmid copy number?
The copy number reflects the average number of copies of a certain plasmid inside a host cell. The higher the copy number, the more efficient the plasmid is at replicating itself. Researchers using plasmids as vectors usually choose high copy number plasmids as their vectors since you can get a large number of plasmids from relatively fewer cells in less time.
When is a plasmid considered a recombinant plasmid?
When the original function of the gene in the plasmid is altered or another gene is inserted in the non- coding region of the plasmid is called the recombinant plasmid.
What is the function of the Ti plasmid?
what is the function of the plasmid
What are two features that make plasmid useful for transforming?
Simple and short DNA sequence and their inherent separation but later group into the genome sequence.
Which is the plasmid that increases resistance to antibiotics?
R-plasmid
What plasmid that can degrade toluic acid?
TOL plasmid
Analogy for plasmid?
F-plasmid (fertility plasmid) of any conjugative bateria or Ti-plasmid (tumor-inducing) of Agrobacterium tumaefaciens.
A plasmid is a type of?
Plasmid is extrachromosomal DNA capable of self replication.
