E. coli expresses a specific gene in the presence of lactose. The expression of this gene is under control by the lac operon, a sequence of nucleotides in the DNA which control the expression of specific enzymes. The image below represents the structure of the lac operon. In order to express the genes identified by (h), (i), & (j), RNA polymerase, which has a low affinity by itself, requires specific events to occur in order to initiate transcription. Which of the following events does not promote the transcription of these genes? DNA ܐ ܐ ܘ ܐ ܐܘ (p) lacl lac Operon (P+ CAP) (0,₁) lacz gene product from (e) binds to (g) CAP binds to (f) lacy lacA allolactose binds to the repressor protein, which reduces the binding to (g) CAMP binds to CAP in the presence of low glucose ODNAPol binds at (j) and begins transcription of (j), then (i), then (h)

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.
