Study Notes
DNA Replication Enzymes
- Helicase is responsible for unwinding the DNA double helix during replication.
- Primase is the enzyme involved in the synthesis of RNA primers during DNA replication.
- The main function of DNA ligase in DNA replication is to seal gaps in the sugar-phosphate backbone of DNA by forming phosphodiester bonds.
- DNA polymerase III is responsible for adding nucleotides to the growing DNA strand during replication.
- Helicase is responsible for unwinding the DNA double helix during replication, creating a replication fork.
- The main function of DNA polymerase III in DNA replication is to synthesize new DNA strands by adding nucleotides to the growing DNA strand.
- DNA ligase plays a crucial role in DNA replication by sealing gaps in the sugar-phosphate backbone of DNA, forming phosphodiester bonds.
- RNA polymerase is not directly involved in DNA replication; it is responsible for transcribing DNA into RNA molecules.
