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.
Best Answer: I have attached a good link. Lets go through the basic process of DNA replication. 1.) DNA helicases unwind the double helix to allow access to the single strands. 2.) A primase lays down an RNA primer 3.) DNA polymerase III begins replication, laying down nucleotides in a 5'-3' direction.(Remember, DNA polymerase has to have an exposed 3' end of a nucleotide in order to bind and initate synthesis)..)
