In the presence of arabinose sugar and absence of glucose, which of the following conditions may be observed at the arabinose operon? Mark all the answers that apply. AraC protein binds to the ara I and ara O2 sites to form a repression loop. Arabinose binds to the CAP protein to cause it to stimulate transcription. The CAP-cAMP complex binds to AraC protein to form a repression loop. The CAP-cAMP complex binds to the CAP-binding site to help stimulate transcription. AraC protein binds to the araI site to stimulate transcription.
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.
