For analysis of the B 1 vitamer content, a 14-mL sample of midlog-phase Chlamydomonas culture was collected by centrifugation at 4,000 × g for 5 min and washed with distilled water three times and weighed. The cells were resuspended in 1 mL 1% (vol/vol) trichloroacetic acid.

T-loops (TLs) are a widespread and versatile RNA motif that stabilizes the tertiary conformation of many non-coding (nc)RNA molecules. 1 The original T-loop was observed in the TΨC-loop of tRNA Phe, where it mediates intramolecular contacts with the D-loop (Fig 1a).2, 3 Subsequently, multiple TLs were discovered in a … navy seal gabe accardi
