Answer:
Cell-mediated immunity develops through a network of interactions that results in defense against microorganisms that survive within phagocytes or other cells. The response is initiated by the recognition of intracellular microorganism antigen by T cells through the histocompatibility complex. In the CD8 response, only the target cell carrying the class I associated antigen can be lysed or induced to apoptosis. In another mechanism of the cellular response, CD4 + Th1 T cells activate, for example, cytokine-infected macrophages such as IFN. When a pathogen resists the effects of activated macrophages, chronic infection may develop.
The hormonal immunity response leads to the destruction of extracellular microorganisms and prevents or decreases the spread of intracellular cells by neutralizing, opsonizing and activating the complement system.

Explanation:
It is most likely due to the fact that the attenuation is the evolutionary relic, which by accident has remained does not support the actual reason of the dual control to regulate the operon.
Answer: Option E
<u>Explanation:</u>
In bacteria transcription and translation carries out at the same time so or the termination of transcription in premature phase in bacteria uses a special mechanism which is called as attenuation T.
he attenuation in bacteria is a regulatory mechanism. Trp operon is the group of codes of the components. These operons are the actual functioning group of the DNA.
