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.
However, DNA does not unzip entirely. It unzips in a small area called a replication fork, which then moves down the entire length of the molecule. Let's look at the details: 1  An enzyme called DNA gyrase makes a nick in the double helix and each side separates. 2  An enzyme called helicase unwinds the double-stranded DNA. 3  Several small proteins called single strand binding proteins (SSB) temporarily bind to each side and keep them separated.
