...left-handed DNA molecule could yield new information about gene activity and could also contribute to the understanding of cancer and basic cell functions, scientists said yesterday...
...group analyzed DNA synthesized by researchers in the Netherlands. However, it has not determined if the new form exists in nature. "Much work remains to be done on this project," Gary J. Quigley, a member of the MIT group, said yesterday...
...past most scientists thought of DNA as a dead molecule" because they thought they completely understood its structure and chemical composition, Quigley said. He added that DNA investigators will have to re-evaluate past findings to see if they hold up in light of the new discovery...
Dressler said that even if the left-handed structure is not proven to exist in natural DNA molecules, the discovery of a DNA structure different from the Watson-Crick model may have important implications...
Rich and his associates are best known for their research into the structure of transfer RNA, an intermediate component of biosynthesis--the DNA synthesis of proteins in the cell. They have been working together for two years and on this particular project for nine months. Their work will appear in the upcoming issue of the British journal. Nature...
