The rate of transcription in bacteria is approximately 40-80 nt per second for an actively transcribed gene. The rate of translation in bacteria is approximately 20 amino acids per second

1. The rate of transcription in bacteria is approximately 40-80 nt per second for an actively transcribed gene. The rate of translation in bacteria is approximately 20 amino acids per second.

 

1. How long will it take to transcribe and translate a protein of 550 amino acids?

 

2. Considering that a codon consists of three bases, the rates of transcription and translation in bacteria are fairly similar on an amino acid basis. (In other words, of the total time needed to express a gene, about half is transcription and about half is translation.) What might be a consequence if one process occurred more rapidly than the other in bacteria?
3. In eukaryotes, the rates of transcription and translation are not as similar as they appear to be in bacteria, with translation being somewhat slower. What is the reason that the rates of transcription and translation in eukaryotes might not be similar?
