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.
Draw the structure of lac operon?
The operon is a unit of DNA (deoxyribonucleic acid) in which multiple genes that function in the same pathway are clustered together. They have a common promoter that transcribes the downstream genes as a single unit called polycistronic messenger RNA (ribonucleic acid). The translation of each gene occurs separately to produce distinct proteins. This is due to the presence of different ribosome-binding sites for each gene of the operon. This type of arrangement is found in prokaryotic genomes.
