Reguleerimisvõrk

Reguleerimisvõrk, also known as a regulatory network, is a system of interactions between genes and proteins that controls the expression of genes. This control is crucial for cellular processes and organism development. Regulatory networks are complex and involve various components, including transcription factors, which are proteins that bind to specific DNA sequences to activate or repress gene transcription. Other elements include microRNAs, small RNA molecules that can bind to messenger RNA and inhibit translation, and epigenetic modifications, which alter DNA accessibility without changing the underlying sequence.

The study of regulatory networks helps us understand how cells respond to internal and external signals, how diseases arise from disruptions in these pathways, and how to develop targeted therapies. Computational tools and experimental techniques are employed to map these intricate connections and predict their behavior. Understanding the dynamics of regulatory networks is fundamental to fields like systems biology, molecular biology, and genetics. These networks are not static but are dynamic, adapting to changing cellular conditions and environmental influences, ensuring the proper functioning and survival of the organism.
