Introns: A Mystery Renewed
December 10, 2009
The sequences of nonsense DNA that interrupt genes could be far more important to the evolution of genomes than previously thought, according to a recent Science report by Indiana University-Bloomington and University of New Hampshire biologists. Their study of the model organism Daphnia pulex (water flea) is the first to demonstrate the colonization of a single lineage by "introns," as the interrupting sequences are known.
The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2017, its budget is $7.5 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives more than 48,000 competitive proposals for funding and makes about 12,000 new funding awards.
