Solution and Explanation
Innate Immunity:
- Innate immunity is the body’s first line of defense against pathogens. It is present from birth and provides a non-specific response.
- Components: Skin, mucous membranes, phagocytes, and natural killer cells.
- Response time: Immediate or within hours of exposure.
- Example: The inflammation response when a pathogen is detected.
Acquired Immunity:
- Acquired immunity develops after exposure to a pathogen. It is specific to the pathogen and has a memory component.
- Components: T-cells and B-cells, which produce antibodies.
- Response time: Slower initially but faster upon subsequent exposure due to memory cells.
- Example: Immunity developed after vaccination or infection (e.g., immunity to chickenpox after infection).
Final Answer: Innate immunity is the body’s immediate, nonspecific defense, while acquired immunity is specific and develops after exposure to a pathogen.
Final Answer: Innate immunity is the body’s immediate, nonspecific defense, while acquired immunity is specific and develops after exposure to a pathogen.

The vector, shown in the figure, has promoter and RBS sequences in the 300 bp region between the restriction sites for enzymes X and Y. There are no other sites for X and Y in the vector. The promoter is directed towards the Y site. The insert containing only an ORF provides 3 fragments after digestion with both enzymes X and Y. The ORF is cloned in the correct orientation in the vector using the single restriction enzyme Y. The size of the largest fragment of the recombinant plasmid expressing the ORF upon digestion with enzyme X is ........... bp. (answer in integer)
