A newly discovered insect has a genomic DNA that does not contain any repetitive DNA or any intronic regions. The insect’s genomic DNA has been treated with the restriction enzyme EcoRI. One of the fragments (with a length of 4 kb) produced in this manner is isolated and ligated into a pUC19 plasmid vector that has also been treated with EcoRI. This recombinant construct is called plasmid A. Samples of plasmid A, pUC 19, and the total genomic DNA from the insect are digested completely with the restriction enzyme EcoRI. The three digests are loaded into separate wells: plasmid A (lane 1), pUC19 (lane2) and total insect genomic DNA (lane 3) of an agarose gel and subjected to electrophoresis. 2b. Draw what will be seen in each lane if the gel is transferred to a membrane and subjected to Southern blotting and the 4000 base pair genomic DNA fragment (labeled with a fluorescent tag) from the insect is used to probe the blot.
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.
