Calculate the minimum length of time required for E. coli RNA polymerase to synthesize an mRNA that encodes a 100 kDa protein. The molecular weight of an amino acid is approximately 110 Da. E. coli RNA polymerase has a transcription rate of approximately 50 nucleotides per second. Round your answer to the nearest whole number.

Step 1
Given that the molecular weight of an amino acid is approximately 110 Da, we can calculate the number of amino acids as follows: \[ \text{Number of amino acids} = \frac{100,000 \text{ Da}}{110 \text{ Da/amino acid}} \approx 909 \text{ amino acids} \] Show more…

How long would it take for the E. coli RNA polymerase to synthesize the primary transcript for the E. coli genes encoding the enzymes for lactose metabolism, which is a 5,600 bp lac operon? Assume an average elongation rate of 70 nucleotides per second. Give the duration in seconds (do not include the seconds unit)

Controlling the rates of transcription and translation is important in bacteria to avoid collisions between ribosomes and RNA polymerases. Calculate what the maximum rate of translation by a ribosome in a bacterial cell would have to be, in units of amino acids per second, so as not to overtake an RNA polymerase that is transcribing mRNA at a rate of 60 nucleotides per second. How long would it take for this bacterial cell to translate an mRNA containing 1800 codons?
RNA Polymerase (a) How long would it take for the $E .$ coli RNA polymerase to synthesize the primary transcript for the $E$. coli genes encoding the enzymes for lactose metabolism, the 5,300 bp lac operon (considered in Chapter 28 )? (b) How far along the DNA would the transcription "bubble" formed by RNA polymerase move in 10 seconds?
