WebPrimase is the enzyme that synthesizes RNA primers, oligonucleotides that are complementarily bound to a nucleic acid polymer. Primase is required because DNA polymerases cannot initiate polymer synthesis on single-stranded DNA templates; they can only elongate from the 3’-hydroxyl of a primer. WebPrimases tend to initiate synthesis at specific three nucleotide sequences on single-stranded DNA (ssDNA) templates and for E. coli DnaG the sequence is 5'-CTG-3'. [1] DnaG …
