1.Your goal is to design a strategy to create thisfinal pDHFR plasmid for fusion protein expressionfrom the materials available:You have an empty pET21a expression vector and another vectorthat contains the fusion protein nucleotide sequence (pBluescript + GST-DHFR-His). (#) indicatesbp location ofenzyme cut: a.EcoRIonly, HindIII only, NotIonly, EcoRI and HindIII, EcoRI and NotI, or HindIII and NotI? b.Briefly explain the rationale for your selection. Please connect your rationale to the need for compatible ends without any further manipulation and required directionality of the DHFR fusion protein coding sequence relative to the T7 promoter that will drive its expression. c.What is the final size(kb)of your desired pDHFR plasmid ligation product based onyour design? d. Complete the chart providedto indicate thesize of all fragments(in bp)resultingfrom complete digestion of each plasmid givenyour strategy, andthe fragment(in kb)from each you would isolate for ligation.Please mind units.
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.
