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.
Making the world better, one answer at a time. The double helix of the DNA unwinds. Then, the enzyme helicase 'unzips' the DNA by breaking the hydrogen bonds. Then, the enzyme DNA Polymerase pairs each of the two strands with the correct nitrogenous bases.The top strand is called the 'leading strand' and the bottom strand is called the 'lagging strand.' Then the enzyme ligase glues together the different fragments of the lagging strand of DNA.Now we have two exact replications of DNA, each with 46 chromosomes called daughter cells.he top strand is called the 'leading strand' and the bottom strand is called the 'lagging strand.'
