A scientist engineers a virus that contains the gene thought to provide bacterial resistance to the antibiotic vancomycin. The s
cientist then takes a culture of bacteria and divides it in two. One portion is allowed to incubate with the previously mentioned virus, while the other is not. Both bacterial cultures are then placed onto petri plates whose media contain vancomycin. Only the culture grown previously with viruses shows growth of bacterial colonies. How did these bacteria FIRST come to have resistance to this antibiotic? Selected Answer: Transformation Bifurcation Transduction Transformation Conjugation
Bacteriophages (or phages) are viruses known for its ability to contaminate and become a parasite in a bacteria. These phages can pass its DNA from a single bacterium to another bacterium, via a means referred to as genetic transduction.
This is believed to be the centre route through which bacteria evolve and possess the antibiotic resistance and virulence factors that increases the formation of new and an increasingly more pathogenic strains.
The mechanisms of genetic transduction includes generalized and specialized transduction.
Explanation: Race is a heritage that various and diverse group of people use to identify with each other. Race may include physical characteristics such as the skin color example the black race and other associated traits such as facial features and hair texture
The functions of nucleic acids have to do with the storage and expression of genetic information. Deoxyribonucleic acid (DNA) encodes the information the cell needs to make proteins.
