Question

VIRUS

  • who do they multiply (compare and contrast Lytic cycle to Lysogenic cycle)
  • what are the parts (include diagram)
  • what is reverse transcriptase (how does it work)
  • why do they steal cell membranes
  • why are they not considered alive

Step 1

Hi, thank you for your question. Since we are entitled to answer the first three parts of a question. I would be answering the first three parts of your query. If you need help with other parts, kindly repost the question and put up a new request.

The question asks about the Virus:

(a). Who do they multiply (compare and contrast Lytic cycle to Lysogenic cycle).

(b). What are the parts (include diagram).

(c). What is reverse transcriptase (how does it work).

Step 2

Viral replication can be defined as the formation of biological viruses during the process of infection in the target host cells. Viruses must enter into the cell before the viral replication can take place. Viruses can reproduce by either the lytic or lysogenic life cycles.

 

Part (a).

The comparison between the lytic and lysogenic cycle is shown in the given table:

Criteria for comparison

Lytic cell cycle

Lysogenic cell cycle

1. Begin of infection.

It begins with the attachment of the bacteriophage to the host cell.

It begins just like the lytic life cycle or previously integrated viral DNA with the host DNA.

2. Types of phages present.

Bacteriophages that only use the lytic cycle are known as virulent phages.

Bacteriophages that use the lytic cycle and lysogenic are known as temperate phages.

3. Location of viral DNA

It exists as a separate and free-floating molecule within the host cell.

It is located within the host DNA.

4. Replication of viral DNA.

It replicates separately from the host cell DNA.

It replicates along with the host DNA.

5. Effect on host cell.

It leads to the destruction or lysis of the infected cell.

It leads to incorporation of phage into the host genome.

 

Step 3

Part (b).

All the viruses have the following main parts that are shown in the figure on board:

  1. A nucleic acid genome: All viruses have nucleic acid either DNA or RNA as its genetic material.
  2. A protein capsid: It is a protein covering around the genome of a virus. It forms nucleo-capsid together with the nucleic acid genome. It is formed of several oligomeric structural subunits tha...
