RNA-polymerase I

RNA polymerase I is an enzyme found in cells that is responsible for synthesizing ribosomal RNA (rRNA), a crucial component of ribosomes, which are the cell's protein-making machines. This enzyme reads the DNA sequence of specific genes and builds RNA strands that will help form ribosomes, enabling them to produce proteins essential for various cellular functions. RNA polymerase I plays a vital role in protein synthesis and, by extension, in maintaining the overall function and health of the cell.
