Concept explainers

Viral Replication

The virus is acellular and considered non-living outside the host cell. The replication of the virus occurs only inside the living cells. Only a few genes are present in the smallest virus, whereas many genes are present in the largest virus. These genes encode specific viral proteins.

Question

In which bacteriophage life cycle does the phage DNA become incorporated into the bacterial chromosome?

a. Lytic

b. Lysogenic

c. Both lytic and lysogenic

d. Neither lytic nor lysogenic

Expert Solution

Step 1

The viruses that infect bacteria are known as bacteriophages and they played a central role in genetic research. They have small and easily manageable genomes, reproduce rapidly and can produce large number of progeny. The two alternative cycles of bacteriophages are: lytic cycle and lysogenic cycle.

Viruses are host-specific, meaning they can only infect specific types of host organisms. For examble, the adenovirus is responsible for the common cold in humans but your dog can't catch a cold from you. Why is this? The proteins on the virus surface can only bind with proteins on the correct host surface. It is an enveloped or non-enveloped virus. The enzymes carried by the virus are compatible with the host. The genome of the virus is made of DNA or RNA.
Choose the one answer that fits best. Which of the following statements regarding bacteria is NOT correct? a. During conjugation, two bacteria exchange genetic information directly via pili b. Bacterial populations have a higher mutation rate because their DNA Polymerases do not have proofreading capability c.

Plasmids carry just a few genes and are replicated independently from the bacterial chromosome e. Cocci that are arranged in clusters/bunches are called staphylococci
