The overall reaction rate for the bacterial RNA polymerase can be as fast as 40–50 nucleotides/ second at 37°C for most transcripts; this is about the same as the rate of translation (15 amino acids/sec), but much slower than the rate of DNA replication (800 bp/sec).

The introns in pre-tRNA vary in length from 14 to 60 bases and only single intron is found in each pre-tRNA transcript A pre-tRNA intron is excised in one step  Finally, hydrolysis of GTP and ATP is required to join the two tRNA halves generated by cleavage on either side of the intron.
