Noun. 1. surface tension-a phenomenon at the surface of a liquid caused by intermolecular forces. physical phenomenon-a natural phenomenon involving the physical properties of matter and energy.
The DNA polymerases are enzymes that create DNA molecules by assembling nucleotides, the building blocks of DNA. These enzymes are essential to DNA replication and usually work in pairs to create two identical DNA strands from a single original DNA molecule.he 3'-5' exonuclease activity of the enzyme allows the incorrect base pair to be excised (this activity is known as proofreading). Following base excision, the polymerase can re-insert the correct base and replication can continue forwards.
DNA polymerase enzyme then moves along the exposed bases sequences, creating a new complementary strand as it goes. DNA polymerase reads the exposed code from the 3' to the 5' end and therefore assembles the new strand from the 5' to the 3'.
