Corrections and Clarifications
In the report "A three-dimensional model for the hammerhead ribozyme based on fluorescence measurements" by T. Tuschl et al. (4 Nov. 1994, p. 785), the text of lines 28 through 30 in column 3 on page 785 should have read, "... we located 5-carboxyfluorescein at (d, 29.5°, L-3.75 Å) and 5-carboxytetramethylrhodamine at (a, 29.5°
, 3.75 Å)." In the same report, the second line of equation 1 in the legend to figure 3 was incorrectly printed. The correct equation appears below.
