Quantum Effects and Genetics Code: Dynamics and Information Transfer in   DNA Replication
  The possible role of quantum effects in transfer of genetic information is studied. It's argued that the nucleotides selection during DNA replication is performed by means of proton tunneling between nucleotide and DNA-polimerase bound by hydrogen bonds. Such mechanism is sensitive to the structure of nucleotide hydrogen bonds, consequently only one nucleotide sort is captured by DNA-polimerase in each event.The algorithm of this multistep selection mechanism is also analysed from the point of its optimality. It's shown that it's equivalent to Grover algorithm of data base search.
