When lactose is first introduced into the medium, the lac operon is not induced and thus permease isn't induced. How is it possible for lactose to enter the cell before the lac operon is induced?
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.
| While the lac operon is not induced yet, lactose has many different ways to get into the cells without the need of permease. | ||
|
||
| While the lac operon is not induced yet, there is always a very high level of permease and beta galactosidase in the cell. | ||
| While the lac operon is not induced yet, there is full level expression most of the time which allows a sufficient amount of permease to be expressed. This allows lactose to enter the cell. | ||
| While the lac operon is not induced yet, there is low level expression most of the time which allows a small amount of permease to be expressed. This allows lactose to enter the cell at low levels. |
