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.
Helicase and RNS polymerase are used in the nucleus. The helicase enzyme is used to unzip the Dna strand in order for the RNA polymerase to copy the genetic code from the Dn â¦ a strand and copy it to the newly formed mRNA strand.1 person found this useful. 1  An Overview of the Enzyme Presoak Stains are simply a natural part of life.he helicase enzyme is used to unzip the Dna strand in order for the RNA polymerase to copy the genetic code from the Dn â¦ a strand and copy it to the newly formed mRNA strand. 1 person found this useful.
