Question:
How long does the DNA--> Messenger RNA --> amino acids formation --> protein synthesis process take? Seconds? minutes?



Replies:
Once transcription is initiated, RNA polymerase can string nucleotides together at a rate of about 30 nucleotides per second. An "average" sized RNA of 5000 nucleotides would take about 3 minutes at 37C.

The complete synthesis of a protein takes 20 to 60 seconds on average.

Translation of a few hundred amino acids off an mRNA transcript takes a second or so.
