What genes does the pREP4 plasmid encode?

Plasmid contains the Epstein-Barr Virus replication origin (oriP) and nuclear antigen (encoded by the EBNA-1 gene) to permit extrachromosomal replication in human, primate and canine cells. Hygromycin B resistance gene can be used for stable selection in transfected cells.

What is pREP4?

pREP4 is an episomal mammalian expression vector that uses the Rous Sarcoma Virus long terminal repeat (RSV LTR) enhancer/promoter for transcription of recombinant genes inserted into the multiple cloning site.

How are bacterial plasmids used in molecular biology?

Plasmids naturally exist in bacterial cells, and they also occur in some eukaryotes. Often, the genes carried in plasmids provide bacteria with genetic advantages, such as antibiotic resistance. Then, because bacteria divide rapidly, they can be used as factories to copy DNA fragments in large quantities.

What is a plasmid and what is it’s significance in molecular biology?

A plasmid is a small, extrachromosomal DNA molecule within a cell that is physically separated from chromosomal DNA and can replicate independently. In nature, plasmids often carry genes that benefit the survival of the organism and confer selective advantage such as antibiotic resistance.

What are the three types of plasmids?

Key Takeaways

  • Plasmids can be found in all three major domains: Archaea, Bacteria, and Eukarya.
  • Plasmids provide a mechanism for horizontal gene transfer within a population of microbes and typically provide a selective advantage under a given environmental state.

How many types of plasmid are there?

There are five main types of plasmids: fertility F-plasmids, resistance plasmids, virulence plasmids, degradative plasmids, and Col plasmids.

What are the 4 steps in gene cloning?

In the classical restriction enzyme digestion and ligation cloning protocols, cloning of any DNA fragment essentially involves four steps:

  1. isolation of the DNA of interest (or target DNA),
  2. ligation,
  3. transfection (or transformation), and.
  4. a screening/selection procedure.

What is the difference between a plasmid and a vector?

The key difference between plasmid and vector is that plasmid is a type of vector and is a circular, double-stranded extra-chromosomal DNA molecule of some bacterial species while vector is a self-replicating DNA molecule that acts as a vehicle for delivering foreign DNA into host cells.
