Question

question 8 (1 point) saved a cloning host has the following desirable features except fast growth rate. pathogenicity. well - mapped genome. keeps foreign genes intact. question 9 (1 point) saved some antiviral agents are activated by viral enzymes. true false question 10 (1 point) saved microbial antagonism means that good microbes are replaced by invading pathogenic microbes. good microbes establish themselves in the host and prevent invasion by pathogenic microbes. the host is predisposed to disease due to the microbes they harbor. pathogenic bacterial growth is encouraged by the presence of established host organisms.

Explanation:

• Question 8: A cloning host should not be pathogenic as it could pose risks to the cloning process and the environment. Fast growth rate, well - mapped genome, and keeping foreign genes intact are all desirable for efficient cloning.
• Question 9: Some antiviral agents like nucleoside analogs are activated by viral enzymes. For example, in the case of herpesviruses, the viral thymidine kinase can phosphorylate certain nucleoside analogs, making them active against the virus.
• Question 10: Microbial antagonism is when normal microbiota (good microbes) compete with pathogenic microbes for resources (such as nutrients and space) and produce substances (like bacteriocins) that inhibit the growth of pathogens, thus preventing their invasion.

Answer:

• Question 8: The answer is "pathogenicity".
• Question 9: The answer is "True".
• Question 10: The answer is "good microbes establish themselves in the host and prevent invasion by pathogenic microbes".
