Lagging strand synthesis step one. Location. Term. DNA polymerase III will continue to incorporate DNA nucleotides in the 5' → 3' direction until it runs into the ... Web9. In simple terms: Function of the RNA primer: DNA polymerases need a double-stranded DNA region to which they can attach in order to begin copying the rest of the DNA strand. In order to provide this double-stranded attachment site, RNA primers are added by primase, an RNA polymerase which does not require such an attachment site itself.
