What is pBR322 class 12 biology?

pBR322 is a 4,362-bp ds DNA plasmid cloning vehicle aimed to authorize the easy and rapid formation of cloned recombinant DNA portions. It has two antibiotic resistance genes, an origin of replication, and a multiplicity of functional restriction sites for cloning or subcloning restriction segments.

What is PBR in microbiology?

A photobioreactor (PBR) can be defined as an enclosed, illuminated culture vessel designed to control biomass production through adjustment of the operating parameters.

What is the use of pBR322?

clone selection. Plasmid pBR322 is used extensively in genetic engineering. It has two genes of special interest. One codes for a protein that enables any host bacterium to resist the lethal effects of the antibiotic ampicillin and the other confers resistance to tetracycline.

What does ROP stands for in the structure of pBR322?

The gene ‘rop’ present in pBR322 cloning vector, codes for the proteins involved in the replication of the plasmid. So, the correct option is ‘Option B’ .

What does 322 mean in pBR322?

the order of synthesis
pBR322 is an artificial plasmid. 322 in pBR322 refers to the order of synthesis and helps in distinguishing it from other plasmids constructed in the laboratory. Further reading: Plasmid.

Is pBR322 an expression vector?

Plasmid vector pBR322 is a well-established multipurpose cloning vector in laboratories worldwide, and a large number of derivatives have been created for specific applications and research purposes, including gene expression in its natural host, E. coli, and few other bacteria.

What does PBR stand for in biology?

Who discovered plasmid?

Joshua Lederberg
The word ‘plasmid’ was first coined by Joshua Lederberg in 1952. He used it to describe ‘any extrachromosomal hereditary element’. Lederberg first used the term in a paper he published describing some experiments he and his graduate student Norton Zinder conducted on Salmonella bacteria and its virus P22.

What is PBR in biotechnology?

pBR322 is a plasmid and was one of the first widely used E. coli cloning vectors. pBR322 is 4361 base pairs in length and has two antibiotic resistance genes – the gene bla encoding the ampicillin resistance (AmpR) protein, and the gene tetA encoding the tetracycline resistance (TetR) protein.
