A student wishes to transform some E. coli with a plasmid to “knock-out” (ie. “silence” or prevent) the activity of Gene X, a gene important in the metabolism of Nutrient X. If Gene X is expressed, it can metabolize Nutrient X, contained within the agar plates, to produce neon orange colonies. To perform this transformation, the student knows that a plasmid must be used. You can assume that the materials this student has to perform their transformation are the same as those you had to complete lab #3. With the above in mind, please answer the following
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.

To perform this transformation, the student knows that a plasmid must be used. You can assume that the materials this student has to perform their transformation are the same as those you had to complete lab #3. With the above in mind, please answer the following - a) What is a plasmid and why does this student need to use one to perform their transformati
- b) How should the student build their plasmid? Identify and briefly describe three key components they should include in their plasmid.
- c) Explain how the student can make their bacterial cells competent to receive their plasmid DNA. (3 pts.)
