Study Notes
DNA Polymerase and DNA Synthesis
- DNA polymerase (DNA Pol) is an enzyme responsible for adding nucleotides to the 3' end of a growing DNA strand.
- Nucleotides are added in a 5' to 3' direction, meaning the new nucleotide is added to the free 3'-hydroxyl group of the previous nucleotide.
- The substrates used for DNA synthesis are deoxyribonucleoside triphosphates (dNTPs), which are composed of a deoxyribose sugar, a phosphate group, and a nitrogenous base.
- DNA Pol adds nucleotides based on complementary base pairing with the template strand, ensuring accurate replication of the genetic code.
- This process involves hydrogen bonding between complementary base pairs (A with T, and G with C).
