Microbiology Quiz #41: Viral structure and genetics

1. A researcher is studying a virus that changes its antigenic properties by exchanging gene segments with a different strain of the same virus when they infect the same host cell. This process is known as: 

Question 1 of 5

2. A virology student learns about a phenomenon where two viral particles infect the same cell and one virus provides a missing functional protein for the other, allowing both to replicate. This process is best described as: 

Question 2 of 5

3. During a virus replication cycle, two viruses enter the same host cell and their capsids mix, resulting in progeny viruses with a mixture of the parental capsid proteins. However, their genomes remain unchanged. This process is known as: 

Question 3 of 5

4. A newly discovered virus has the ability to exchange genetic material with another virus by breaking and rejoining their DNA strands when they coinfect a host cell. This genetic exchange mechanism is best described as: 

Question 4 of 5

5. Which of the following viral processes is primarily responsible for the rapid evolution of RNA viruses, allowing them to evade host immune responses through minor antigenic changes? 

Question 5 of 5
