Answer:
Acetylcholine
Explanation:
Acetylcholine (ACH) is a neurotransmitter hormone produced by the nervous system (central and peripheral), which is released by the motor nerve endings in the muscle. It is a simple molecule produced in the cytoplasm of nerve endings, being derived from choline (component of lecithin), which arises from its reaction with acetyl-CoA in the presence of the enzyme choline acetyl transferase (ChAT).
This hormone acts in various parts of the body as a messenger between nerve cells, and its main effects are on the cardiovascular system, excretory system, respiratory system, muscle system and the brain.

<span>Most viruses have RNA genomes that are replicated and transcribed into messenger RNA by viral RNA-dependent RNA polymerases (RdRps), usually in concert with other viral and host factors. Many, if not most, eukaryotes also encode putative RdRps that have been implicated in sequence-specific, RNA-triggered gene silencing. Although the viral and cellular RdRps have no sequence homology, they share functional similarities such as copying messenger RNA templates and intercellular spread of the amplified sequences. Better understanding of viral and host RdRps will improve our ability to control viruses and to use RNA silencing and viruses as tools for research, biotechnology, and medicine.</span>
