Three pairs of bacterial cells with the given genotypes undergo conjugation. Place match the genotype of each cell after conjugation to its initial genotype. F+ x F- Hfr F- F' F- Answer Bank F F F+ Hfr What is the role of the F-factor in conjugation? O It contains genes necessary for replication of the donor's F plasmid. It allows auxotrophic bacterial cells to survive on minimal medium so that conjugation can occur. It contains genes that force recombination between the donor and recipient chromosomes. O It contains genes necessary for the formation of the pilus. O It degrades the chromosome of the recipient cell after conjugation.
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.
