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.
Daughter strand-Refers to the newly synthesized strand of DNA that is copied via the addition of complementary nucleotides from one strand of pre-existing DNA during DNA replication. DNA Helicase-The enzyme responsible for separating the two strands of DNA in a helix so that they can be copied during DNA replication.rimase-The enzyme responsible for initiating synthesis of RNA primers on the lagging strand during DNA replication. Holoenzyme-A term used to describe a collection of different enzymes that work together in a given process such as DNA replication.
