Messenger RNA (mRNA) plays a crucial role in the process of DNA transcription, as illustrated by C018 / 0900. During this process, an RNA polymerase molecule (F006 / 9475) binds to the DNA template strand and synthesizes a complementary mRNA molecule. This newly formed mRNA carries genetic information from the DNA and serves as a blueprint for protein synthesis. Once synthesized, mRNA requires various factors for its proper functioning. One such factor is SelB elongation factor, which can be seen bound to RNA in F006 / 9648. SelB elongation factor assists in delivering specific amino acids to the ribosome during translation, ensuring accurate protein synthesis. Speaking of ribosomes, bacterial ribosomes are responsible for protein synthesis and can be observed alongside mRNA molecules in action. The intricate dance between these components leads to the creation of functional proteins necessary for cellular processes. To protect and stabilize mRNA molecules, Poly (A)-binding proteins form complexes with them. These complexes aid in regulating gene expression and maintaining the integrity of mRNA throughout its lifespan. Furthermore, iron-regulatory proteins play a vital role in controlling iron metabolism within cells by binding to specific regions on RNA molecules (C015 / 6691 & C015 / 6690). This interaction helps regulate iron levels essential for numerous biological functions. Overall, messenger RNA acts as an intermediary between DNA and protein production machinery. Its formation through DNA transcription involving RNA polymerase molecules (C016 / 2391 & C016 / 2390) enables genetic information transfer from genes to functional proteins via translation at ribosomes.
