The process of DNA replication can't be initiated with out a primer. The primers are short DNA or RNA sequences which are complementary to the existing DNA strands.

These RNA nucleotides are primers allowing DNA Polymerase III to attach. DNA Polymerase III is the main workhorse of DNA replication, matching up D-nucleotides to the opened parental DNA strand. The RNA primer allows DNA Polymerase III to attach and provides a hydroxyl (OH) group so the first D-nucleotide can be matched up with the parental strand.

A primer is a short single-stranded nucleic acid utilized by all living organisms in the initiation of DNA synthesis.The enzymes responsible for DNA replication, DNA polymerases, are only capable of adding nucleotides to the 3’-end of an existing nucleic acid, requiring a primer be bound to the template before DNA polymerase can begin a complementary strand.

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.

A primer must be synthesized by an enzyme called primase, which is a type of RNA polymerase, before DNA replication can occur. The synthesis of a primer is necessary because the enzymes that ...

DNA REPLICATION: Before the lagging-strand DNA exits the replication factory, its RNA primers must be removed and the Okazaki fragments must be joined together to create a continuous DNA strand. The first step is the removal of the RNA primer. RNAse H, which recognizes RNA-DNA hybrid helices, degrades the RNA by hydrolyzing its phosphodiester ...

Hyone-Myong Eun, in Enzymology Primer for Recombinant DNA Technology, 1996. ii. Physiological roles of RNase H. Despite multiple roles proposed for RNase H, for example, the removal of RNA primers from Okazaki fragments during DNA replication, no in vivo roles have been clearly established in eukaryotes (56).In fact, the physical differences between eukaryotic and prokaryotic RNases H and ...

Okazaki fragments are then synthesized via extension of these RNA primers by DNA polymerase. An important consequence of such RNA priming is that newly synthesized Okazaki fragments contain an RNA-DNA joint, the discovery of which provided critical evidence for the role of RNA primers in DNA replication.
