polymerase II

Polymerase II is a crucial enzyme found in cells that helps produce messenger RNA (mRNA) from DNA. Think of it as a copier that transcribes the instructions encoded in our genes into a readable format. This mRNA then acts like a blueprint for building proteins, which perform various functions in the body. Polymerase II plays a vital role in gene expression, allowing cells to respond to their environment and maintain proper function. In essence, it helps translate the genetic information necessary for life into practical applications within the cell.
