WebAs with all polymerases (be it RNA or DNA) nucleotides are added to the 3’ end of an existingstrand. Primases add a short stretch of RNA, which serves as the initial strand upon which DNA polymerases will elongate (this short, “starter stretch” of RNA will later be removed by a polymerase and replaced by DNA). chewing fearWebFeb 26, 2003 · A major function of DNA polymerases is to accurately replicate the six billion nucleotides that constitute the human genome.
