Geneticist Ray Wu dies

Geneticist and genetic engineering pioneer Ray Wu died on February 10 of cardiac arrest. He was 79. In 1970, Wu developed a new location-specific primer-extension technique that became the first method of sequencing DNA. In the following decade, Frederick Sanger adapted the approach for faster sequencing, and received the Nobel Prize in Chemistry for the work in 1980. Wu's lab also devised other approaches that were used to analyze genetic sequences and to construct vectors for cloning genes,
