What is the pARA-R plasmid?

What is the pARA-R plasmid?

The pARA plasmid contains the ori and necessary regulatory components for gene expression but does not contain a gene of interest. The complete pARA-R plasmid will contain the ori, the gene of interest (rfp) under the control of the pBAD promoter, and the selectable marker antibiotic resistance to ampicillin (ampR).

What is a plasmid map?

Plasmid maps are graphical representation of plasmids, that show the locations of major identifiable landmarks on DNA like restriction enzyme sites, gene of interest, plasmid name and length etc.

How do the cells in the P+ culture differ from the cells in the P culture?

The P+ culture contains the recombinant plasmid with the rfp gene and pBAD, while the P- culture only contains competent bacteria cells and luria broth. The difference will be that the P+ culture, with arabinose present, will glow red.

Who Discovered R plasmid?

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 encoded by genes on an R plasmid?

R-factors are pieces of DNA, usually plasmids, that contain antibiotic resistance genes. Resistance genes are ones that give rise to proteins that modify the antibiotic or pump it out.

How do plasmid maps work?

Working a DNA into mapping is done using restriction endonuclease enzymes that are found in bacteria, to cut the DNA into fragments. These enzymes cut specific recognition sites of a DNA molecule which may result in a sticky end i.e. over hangs using EcoR1 in the 5’G-AATTC 3′.

How does the P tube differ from the P+ tube quizlet?

Difference between the P+ and P- tubes. Bacteria in P+ tube were given plasmid and bacteria in P- tube were not given plasmid. Specific piece of genetically engineered circular DNA introduced into P+ tube.

Which of the following functions can the pKAN-R plasmid carry out when present in bacterial cells quizlet?

Which of the following functions can the pKAN-R plasmid carry out when present in bacterial cells? Initiate transcription of the rfp gene. -Produce a protein that allows bacteria to survive in the presence of that antibiotic Kanamycin.

Where is the R plasmid found?

bacteria
They are a small, circular piece of DNA molecules that replicate independently of the bacterial chromosomes. Plasmids are mainly found in bacteria, Achaea and other multicellular organisms.
