Distributions of lifetimes and elongation rates measured for exponentially growing cells

1. The lifetimes of 847 transcripts were measured, with an average lifetime of 2.5 min (standard deviation 2.5 min).
2. The elongation rates for 263 transcripts longer than 1,200 nt were measured. The average is 25 nt/s (standard deviation 14 nt/s).
