The interrupted non-coding regions in pre-mRNAs, termed «introns,» are excised by «splicing» to generate mature coding mRNAs that are translated into proteins. As human pre-mRNA introns vary in length, the splicing mechanisms and factors involved are likely not universal. A study by researchers from Fujita Health University in Japan reportsContinuar Leyendo
Thousands of COVID-19 cases and deaths in California, Oregon, and Washington between March and December 2020 may be attributable to increases in fine particulate air pollution (PM2.5) from wildfire smoke, according to a new study co-authored by researchers at Harvard T.H.
