Question

During viral infection the protein formed in host cells to resist is:

• A. Interferone
• B. Antitoxin
• C. Antibody
• D. Histone

Answer 1

The Correct Option is A

In the context of viral infections, the host cells have several mechanisms to resist the virus and minimize its impact. One of the key proteins formed by host cells in response to viral infections is known as Interferon. Let's explore why this is the correct answer and also discuss why the other options are incorrect:

Step-by-Step Explanation:

1. Understanding Interferon:
   • Interferons are a group of signaling proteins that are produced and released by host cells in response to the presence of pathogens, such as viruses, bacteria, and parasites.
   • When a virus infects a host cell, the cell releases interferons to alert nearby cells to the viral threat. This helps to activate immune responses that inhibit viral replication within the host.
   • Interferons boost the immune system by enhancing the actions of various immune cells and inhibiting viral replication.
2. Explanation of Other Options:
   • Antitoxin: Antitoxins are antibodies that neutralize toxins. They are not typically produced in response to viral infections but are more relevant in bacterial exotoxin neutralization.
   • Antibody: Antibodies are proteins produced by B-cells that specifically target pathogens. While antibodies do play a crucial role in combating viruses, their production is more specific and usually follows the primary signaling and response by interferons.
   • Histone: Histones are proteins associated with DNA structure and gene regulation in the nucleus of eukaryotic cells. They are not involved in direct viral defense mechanisms.
3. Conclusion:
   • Given that interferons are integral to the initial immune response to viral infections, they are the correct answer to the question of which protein is produced by host cells to resist viral infections.
   • Thus, Interferone (correctly spelled Interferon) is the accurate choice.
