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.
DNA polymerase III (not DNA polymerase) is an enzyme that works in association with other enzymes during the replication of a DNA molecule.DNA replication begins when the enzyme, known as helicase unwinds a DNA strand. Helicase unwinds a DNA strand, thus, in the process, separating the two DNA templates.The result of the unwinding of the DNA molecule is the formation of a replication bubble. Once a DNA molecule is unwound, it is not stable.NA replication begins when the enzyme, known as helicase unwinds a DNA strand.
