A Brief Explanation of an Over-the-Counter Market | Definition. A over-the-counter market (OTC) refers to a decentralized and informal way of exchanging stocks, derivatives, or other assets between two parties.
The leading strand is built by using the lagging strand of the old molecule as the template. Replication of the leading strand begins with the enzyme âprimaseâ. Primase adds a small complementary piece of RNA (~10 nucleotides), called an âRNA primerâ, near the end of the lagging strand. The RNA primer gives an enzyme called âDNA polymerase IIIâ something to attach a DNA nucleotide to. A jury-rigged design, RNA primers are necessary because DNA polymerase III can only attach nucleotides to the 3â end of a pre-existing nucleotide.
The following is a list of major DNA replication enzymes that participate in the replisome: Enzyme Function in DNA replication Also known as helix destabilizing enzyme. Unwinds the DNA double DNA Helicase helix at the Replication Fork. Builds a new duplex DNA strand by adding nucleotides in the 5' to 3' DNA Polymerase direction. Also performs proof-reading and error correction.
