Power of Sale. 1  Some title companies draft and insure land contracts that contain a Vendor, a Vendee and a Trustee.  Like a trustor in a trust deed, the Vendor and Vendee assign right, title and interest to the trustee for the purpose of securing the Vendor's and Vendee's obligations.
When DNA is replicated, hydrogen bonds between the complementary bases are broken to allow for the double helix DNA strand to unzip.he hydrogen bonding between the base pairs must be broken to  separate two strands of DNA molecule.
DNA helicase is the enzyme that unwinds the DNA double helix by breaking the hydrogen bonds down the center of the strand. It begins at a site called the origin of replication, and it creates a replication fork by separating the two sides of the parental DNA. This 'unzipping' of the molecules will expose the nitrogenous bases of the nucleic acid chain so that new nucleotides can be added to create the daughter strand.
