Interaction of the HpaI endonuclease with synthetic oligonucleotides
Biochemistry, 1982To determine which functional groups of bases within the grooves of double-helical DNA interact with the HpaI endonuclease, we have employed chemically synthesized octanucleotides containing base analogues. The 5-methyl group of thymine was probed as a contact between the HpaI endonuclease and its recognition sequence by using the oligonucleotides d(G ...

The Role of Wild Birds in the Spread of HPAI H5N1
Avian Diseases, 2007There is much debate about the relative roles of poultry movements and wild bird movements in the spread of highly pathogenic avian influenza H5N1. This article looks at the problem from an ornithologic perspective. Outbreaks in wild birds are examined in relation to three scenarios of possible wild bird involvement in virus transmission.
