Pol

Pol (short for polymerase) is an enzyme that helps copy genetic information in cells. Think of it as a molecular copier that reads a segment of DNA and creates a matching strand of RNA or DNA. This process is essential for cell growth, repair, and reproduction. Pol works by attaching to the DNA and adding nucleotides—the building blocks—one at a time, ensuring the genetic code is faithfully copied. There are different types of polymerases specialized for various functions, such as DNA replication or repairing damaged DNA, and they are vital for maintaining healthy cell function.
