Trifonov unveiled multiple novel codes in biological sequences and the modular structure of proteins. He was raised by his mother, Riva, and his step-father, Nikolay Nikolayevich Trifonov. In his school years, he became interested in medicine and physics.
Trifonov graduated in biophysics from the Moscow Institute of Physics and Technology in 1961 and earned his PhD degree in molecular biophysics there in 1970. Trifonov has been a head of the Genome Diversity Center at the Institute of Evolution at the University of Haifa in Israel since 2002, and a professor at Masaryk University in Brno, Czech Republic since 2007. At the beginning of his scientific career, Trifonov studied characteristics of the DNA with biophysical methods. After his relocation to Israel in 1976, he switched over to bioinformatics, and established the first research group for that discipline in the country. DNA molecule is bent smoothly along its length, with the same angle between every two base pairs. Similar to the hinge model, but with smoother kinks every 5 bp.
Trifonov supported the concept of smooth bending of the DNA. Periodicity of other dinucleotides were confirmed later by Alexander Bolshoy and co-workers. Finally, an ideal sequence of the nucleosomal DNA was derived in 2009 by Gabdank, Barash and Trifonov. In 1979, Trifonov and Thomas Bettecken estimated the length of a nucleosomal DNA repeat to be 10. The newly synthesized protein is folded a module by module, not as a whole. The first ancient codons were GGC and GCC from which the other codons have been derived by series of point mutations. He is on the Board of Directors at Weizmann Impex Service Enterprise Ltd.

Hematopoiesis provides a well-defined model to study chromatin state dynamics, but technical limitations impede profiling of homogeneous differentiation intermediates. 11,201 lineage-specific enhancers, followed by gradual closing of stem cell enhancers during lineage maturation. Combining our enhancer catalog with genome-wide open chromatin sites and gene expression profiles, we elucidate the transcription factor network controlling chromatin dynamics and lineage specification in hematopoiesis.
Together, our results provide a comprehensive model of chromatin dynamics during development. Department of Immunology, Weizmann Institute of Science, Rehovot, Israel. University of Pittsburgh Center for Vaccine Research scientists. And this discovery is particularly exciting because it is the first time that anyone has shown a virus using this particular strategy to evade its host’s immune system and exacerbate disease progression. Klimstra and his colleagues discovered that EEEV evolved to have a binding site in its RNA that fits perfectly with a small piece of RNA, called microRNA, in the cells of the organism that the virus is invading. Typically, microRNAs are produced by the host to control its own cellular processes.
When the virus binds with the microRNA in certain cells involved in triggering an immune response in a human, it restricts its own replication. This allows the virus to evade an immune response because the viral replication in these cells is what would normally tip off the host’s immune system and induce it to mount an attack to rid the body of the virus. Meanwhile, the virus is able to replicate and spread undetected in the cells of the host’s neurological system and cause overwhelming disease. EEEV causes inflammation of the brain that begins with the sudden onset of headache, high fever, chills and vomiting and can quickly progress to disorientation, seizures and coma. There is no treatment for the disease, but it is rare, with about five to 30 cases reported in the U.
Centers for Disease Control and Prevention. It has a 30 to 70 percent fatality rate, the highest of any North American mosquito-borne virus, with significant brain damage in most survivors. It does not transmit easily to humans, and the mosquito species that typically carries it is usually found in swampy areas that aren’t highly populated, though it has been found in more common mosquitoes, spurring pesticide spraying, curfews and outdoor event cancellations in recent years in states such as Massachusetts, where EEEV is more frequently found. Klimstra and his colleagues created a mutant version of EEEV without the microRNA binding site, which allowed them to discover that the binding site is key to the virus evading detection. When this manufactured mutant version was tested in the laboratory, the researchers found that the host’s immune system was able to mount an effective response to the mutant virus. However, the genetic sequence that allows EEEV to bind to our microRNA has persisted. We find it in samples from the 1950s, which indicates tremendous evolutionary selection pressure to maintain this mechanism.
