- Phages that destroy host cell DNA, direct synthesis of phageparticles, and cause lysis of the host cell are called:(a) Temperate phages(b) Prophages(c) Lysogenic phages(d) Virulent phages(e) TransductionsGonorrhea is a sexually transmissible disease (STD) caused by the bacterium Neiserria gonorrhoeae. In the 1940s, penicillin was introduced as an antibiotic to treat gonorrhea. In particular, the drug inhibits the formation of new cell walls in dividing bacterial cells, making new cells vulnerable to the human body's defences. However, a new strain of Neiserria gonorrhoeae was found that is capable of breaking down penicillin, making this strain resistant. The emergence of this new strain has been associated with instances of non-strict compliance of certain patients on the use of penicillin as well as the improper administration of the drug. Based on the information given, formulate a strategy that could help control this new strain.Why is it favorable for protozoa to replicate with schizogony versus using simple mitosis? what are the different scenarios that can occur with regards to bacterial growth within a thioglycolate tube? Explain why certain bacteria require one classification versus a different classification. A botanist has been using betaproteobacteria to grow his herb garden, because betaproteobacteria require little nutrients to grow. His garden does not grow successfully, so he comes to you for help to develop the herb garden. Which class of gram negative bacteria would you suggest and why? Why was the botanist’s original idea not going to work?
