In cloning a specific fragment from a mixture of different fragments of DNA, three classes of plasmids can be produced: vector containing the desired fragment (gene of interest), vector containing other fragments, and re- ligated vector containing no inserted DNA. What class of vector would you expect to find at the highest frequency? Multiple Choice O All three types of vector will be found in approximately equal proportions Vector containing random genomic DNA fragments Vector containing the gene of interest Vector with no insert
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.
