This is the first time that we have identified the detailed structure of the telomerase component from plants, said co-author Dr. Julian Chen, a professor of biochemistry at Arizona State University. The study was published Monday in the Proceedings of the National Academy of Sciences journal.Telomerase is the enzyme that creates the DNA of telomeres, the compound structures located at the tips of our chromosomes. Telomeres protect our cells from aging as they multiply."So in terms of fundamental research, this is a really big breakthrough because now finally we have a way to study telomerase in plants and to understand how different or similar they are from animals," Chen said.Could the discovery possibly lead to humans one day living as long as the fabled "Methuselah" tree, a bristlecone pine species that can live over 5,000 years? Maybe one day."This is really basic research. The application to humans is really a long way away," Chen said.In the meantime, however, experts like 995

There are currently 53 Republicans in the U.S. Senate and 45 Democrats and two Independents, both of whom caucus with the Democrats. Democrats would need to win four seats held by Republicans and retain all of their current seats to win a majority.While Kentucky, Alabama, South Carolina, and Texas are viewed as reaches for Senate Democrats in 2020, the poll suggests Democrats could win in other key states, like Arizona, Colorado, Georgia, Iowa, Maine, and North Carolina.Morning Consult weighted responses in each state separately based on age by gender, race by education, home ownership, marital status, population density, and presidential vote history. There's a 3-point margin of error.This story originally reported by Jordan Mickle on lex18.com. 756
