RNA I~lymetase U subunit functions. Clues to the functions of the subunits. have been obtained from sequence simi-. larities with prokaryotic relatives, from. studies of DNA and nucleotide binding. in vitro, and from the analysis of mutant. defects. The eukaryotic 'core' subunits.
The study found some evidence linking an extended school year to improvement in student achievement. As was found in the research on a longer school day, the effects were not consistent across grades or SES groups.It should be noted there were no randomized controlled trials (RCTs).
