Which of the following statements about Hfr strains of E. coli is FALSE? Group of answer choices Hfr stands for "high frequency recombination" In Hfr strains, the F factor is integrated into the main bacterial chromosome The location and order of genes along the chromosome can be mapped using the time of transfer of different marker genes. Genetic exchange between Hfr and F− strains is studied using the interrupted mating technique In Hfr strains, the F factor is integrated into a plasmid
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.
