During the process of bacterial transcription initiation, an open complex is formed involving the promoter and RNA polymerase. The open complex ________________________________. is the first complex formed between RNA polymerase and the promoter is formed after the sigma factor is released is an unstable transcription initiation complex formed between RNA polymerase and the promoter in the absence of sigma factor is a transcription complex in which an RNA stem-loop structure keeps the DNA strands separated. is a stable transcription initiation complex in which the DNA strands in the promoter region are separated
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.
