The function of DNA in a cell is to code the way proteins turn genes on or off. the function of DNA is to make the proteins. DNA is the foundation of life. It's a complex molecule made up of four types of bases, cross connected like a staircase, and twisted into a spiral.
Lesson Summary. In summary, we have covered what DNA polymerase is and what it does. DNA polymerase is an enzyme that synthesizes new copies of DNA. It carries out this function after DNA helicase has unzipped the DNA thereby creating two single strands of DNA that can be used as templates.he result of DNA polymerase function is two copies of DNA that contain one original and one newly synthesized strand of DNA.
