2018年5月2日 · Rich is perhaps best known for the elucidation of the three-dimensional structure of a transfer RNA molecule, and for the discovery of an alternative form of DNA that exists in …

2018年5月31日 · Alex Rich had a long and fertile career at MIT working on the relationship between the molecular structure and the function of biological information molecules DNA and …

2015年5月20日 · Rich is perhaps best known for his discovery of a DNA structure in which the double helix winds to the left instead of the right. In 1979, he, along with crystallographer …

2015年11月1日 · Rich's biggest discoveries were left-handed Z-DNA, the tertiary structure of tRNA, and that DNA and RNA strands could pair up. His discoveries provided the groundwork …

It has been nearly 63 years since the first characterization of an RNA triple helix in vitro by Gary Felsenfeld, David Davies, and Alexander Rich. An RNA triple helix consists of three strands: A …

2015年5月6日 · For nearly six decades, Dr. Rich, who died at 90 on April 27 in Boston, doggedly investigated DNA and RNA, the fundamental molecules of life. He helped puzzle out the …

The AT-rich genes are prone to be tissue-specific (silenced in most tissues), while the GC-rich genes tend to be housekeeping (expressed in many tissues). This paper reports another …

The top and side views are shown for X‐ray crystal structures (cartoon representation) solved for an RNA triple helix, A‐RNA double helix, A′‐RNA double helix, and B‐DNA double helix. …

Ring Imaging CHerenkov (RICH) detector. RICH detectors utilize the velocity dependence of the emission angle of Cherenkov radiation, to accurately measure relativistic charged particle …
