WebAnswer (1 of 9): Most times in PCR one uses DNA primers. RNA oligonucleotides are much more difficult syntheses with lower yield, so the companies charge a lot more (probably 10X or so). But, RNA primers have been used. This enables the enzymatic destruction of free primers, though there are che... WebThe Okazaki fragment is joined to the expanding strand by DNA ligase. RNA primer= To start the synthesis of DNA, RNA primers are essential. For DNA polymerase to create new strands, they offer the beginning sequence required. The primase enzyme is used to insert the RNA primer at the template DNA location on both the leading and lagging strands.
