Let’s suppose a new strain of P1 phage has been identified thatpackages larger pieces of the E. coli chromosome. This P1 strainpackages pieces of the E. coli chromosome that are 5 minuteslong. If two genes are 0.7 minute apart along the E. coli chromosome,what would be the cotransduction frequency using a normalstrain of P1 and using the new strain of P1 that packages largerpieces? What would be the experimental advantage of using thisnew P1 strain?
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.
Let’s suppose a new strain of P1 phage has been identified that
packages larger pieces of the E. coli chromosome. This P1 strain
packages pieces of the E. coli chromosome that are 5 minutes
long. If two genes are 0.7 minute apart along the E. coli chromosome,
what would be the cotransduction frequency using a normal
strain of P1 and using the new strain of P1 that packages larger
pieces? What would be the experimental advantage of using this
new P1 strain?
