Animal microRNAs

Animal microRNAs are tiny molecules made of RNA that play a crucial role in regulating genes. They help control how genes are turned on or off, influencing various biological processes such as development, immune responses, and cell growth. By binding to messenger RNAs (the templates for protein production), microRNAs can prevent these messages from being translated into proteins or lead to their breakdown. This regulation is essential for maintaining proper cellular function and responding to environmental changes, making microRNAs important players in health and disease in animals, including humans.
