A nanopore-based device provides single-molecule detection and analytical capabilities that are achieved by electrophoretically driving molecules in solution through a nano-scale pore. The nanopore provides a highly confined space within which single nucleic acid polymers can be analyzed at high throughput by one of a variety of means, and the perfect(More)
The MIT Faculty has made this article openly available. Please share how this access benefits you. Your story matters. Accession numbers for all primary sequencing data are given in Supplementary Information. Abstract A variety of microbial communities and their genes (microbiome) exist throughout the human body, playing fundamental roles in human health(More)
The National Science and Technology Council (NSTC) is the principal means by which the Executive Branch coordinates science and technology policy across the diverse entities that make up the Federal research and development enterprise. A primary objective of the NSTC is establishing clear national goals for Federal science and technology investments. The(More)
DNA sequencing-by-synthesis (SBS) technology, using a polymerase or ligase enzyme as its core biochemistry, has already been incorporated in several second-generation DNA sequencing systems with significant performance. Notwithstanding the substantial success of these SBS platforms, challenges continue to limit the ability to reduce the cost of sequencing a(More)
Detachment of the flagella of Chlamydomonas induces a rapid accumulation of mRNAs for tubulin and other flagellar proteins. Measurement of the rate of alpha and beta tubulin RNA synthesis during flagellar regeneration shows that deflagellation elicits a rapid, 4-7-fold burst in tubulin RNA synthesis. The synthesis rate peaks within 10-15 rain, then declines(More)
To investigate the involvement of tubuiin gene expression in controlling cell division events in Chlamydomonas reinhardtii we have measured tubuiin mRNA levels during the cell cycle under different environmental conditions. In C. rein-hardtii cells grown under the synchronizing conditions of 14 h of light followed by 10 h of darkness , mRNAs for tubuiin and(More)
