What is a vector? Which vector did you choose? Explain why you made that choice. What enzyme(s) will you use to place your fragment into the vector? Explain why you chose these enzymes. How will you move this construct into coli?
Bacterial Genomics
The study of the morphological, physiological, and evolutionary aspects of the bacterial genome is referred to as bacterial genomics. This subdisciplinary field aids in understanding how genes are assembled into genomes. Further, bacterial or microbial genomics has helped researchers in understanding the pathogenicity of bacteria and other microbes.
Transformation Experiment in Bacteria
In the discovery of genetic material, the experiment conducted by Frederick Griffith on Streptococcus pneumonia proved to be a stepping stone.
Plasmids and Vectors
The DNA molecule that exists in a circular shape and is smaller in size which is capable of its replication is called Plasmids. In other words, it is called extra-chromosomal plasmid DNA. Vectors are the molecule which is capable of carrying genetic material which can be transferred into another cell and further carry out replication and expression. Plasmids can act as vectors.
Now that you’ve isolated the gene and made lots of copies, you need to insert the gene into something you can manipulate and move into your lab strain of E. coli. You have access to the following vectors, either pBR322 or pUC19 (look them up here to see a map https://www.neb.com/products/dna-plasmids-and-substrates Please note the restriction sites in BOLD appear only once in the plasmid). You may use either vector.
- What is a vector? Which vector did you choose? Explain why you made that choice.
- What enzyme(s) will you use to place your fragment into the vector? Explain why you chose these enzymes.
- How will you move this construct into coli?
- What
phenotype will tell you if the coli have taken up the plasmid? - What phenotype will tell you if the coli have taken up the plasmid with the gasP gene?
