Question

In this chapter, we have focused on genetic systems present in bacteria and on the viruses that use bacteria as hosts (bacteriophages). In particular, we discussed mechanisms by which bacteria and their phages undergo genetic recombination, which allows geneticists to map bacterial and bacteriophage chromosomes. In the process, we found many opportunities to consider how this information was acquired. From the explanations given in the chapter, what answers would you propose to the following questions?

How do we know that genes exist in bacteria and bacteriophages?

Accepted Answer

Hello, everyone. Here we have a question that says the genes found in bacteria consists of D N A while for bacterial pages. It could be D N A R N A or both select which option best describes how geneticists proved the presence of genes and the said organisms. A bacterial conjugation, bacterial conjugation allows genetic material to be passed on from one donor bacteria to the next. So A is correct. B bacterial preference for specific cultural media culture. Media sensitivity allows the genetic isolation of a specific species of bacteria to be grown under laboratory conditions, which helps geneticists prove the presence of genes. So B is correct. See specificity of bacteriophage for certain bacterial species, bacteriophages can infect a certain species of bacteria while leaving others untouched. So C is correct. So our answer here is D all the above. Thank you for watching. Bye.
