Bacteria also produce restriction enzymes, which can cut DNA at specific base sequences. Different restriction enzymes cut different base sequences and some make staggered cuts which leaves unpaired DNA ("sticky ends") and other cut leaving no unpaired DNA ("blunt ends").

In other aspects, the present invention is directed to replicable recombinant cloning vehicles comprising a nucleic acid sequence which codes for a secoisolariciresinol dehydrogenase protein, or to a base sequence sufficiently complementary to at least a portion of a secoisolariciresinol dehydrogenase DNA or RNA to enable hybridization therewith.
Needless to say, the Darwinism-based theories which invariably rely on the particulate concept of gene, DNA base sequence (genome, a chemical structure) as the genetic program and a hypothetical mechanism called natural selection are facing a frontal attack from scientists and the public alike, if the current website debates on Darwinism, the increasing number of books questioning the validity of the theory, and the efforts to remove Darwinism from the school science curriculum are any indication.
To produce this molecule, the DNA double helix untwists temporarily, exposing the base sequence that encodes the protein to be synthesized.
