polymerase

Polymerase is an enzyme that copies long molecules of genetic information, such as DNA or RNA. It reads the sequence of this genetic code and then builds a new, complementary strand by linking together the appropriate building blocks. This process is essential for cell division, gene expression, and DNA repair. Different types of polymerase specialize in copying DNA or RNA, ensuring the genetic instructions are accurately duplicated or transcribed for use within the cell. In summary, polymerase acts as a molecular copy machine, enabling cells to pass on and utilize genetic information efficiently.
