Deoxyribonucleoside triphosphates are the necessary and fundamental monomers for polymerization of DNA. However, DNA replication also requires ribonucleoside triphosphates. Why?More than one answer is correct. Question 8 options: new DNA chains are initiated on an RNA primer synthesized from ribonucleoside triphosphates by primase. DNA helicase uses the energy of ATP (a ribonucleoside triphosphate) to unwind the DNA double helix before DNA synthesis can occur. unlike DNA polymerase epsilon, DNA polymerase delta incorporates ribonucleotides into the growing polymer to synthesize the lagging strand ribonucleoside triphosphates are converted into deoxyribonucleoside triphosphates by DNA polymerase immediately before incorporation. DNA is first synthesized as RNA which is converted to DNA by removal of the 2'-OH (2' hydroxyl) from the pentose sugars in the backbone by DNA polymerase.
