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? assume an average elongation rate of 70 nucleotides per second.

Answers

E. coli RNA polymerase is responsible for synthesizing the primary transcript for genes encoding enzymes involved in lactose metabolism.

These genes are located within the lac operon, which is 5,300 base pairs (bp) long. Given an average elongation rate of 70 nucleotides per second, we can determine how long it would take for the RNA polymerase to synthesize the primary transcript for the lacoperon.
To calculate the time required, we will divide the total length of the lac operon (5,300 bp) by the average elongation rate (70 nucleotides per second):
Time (seconds) = 5,300 bp / 70 nucleotides per second ≈ 75.71 seconds
Thus, it would take approximately 75.71 seconds for the E. coli RNA polymerase to synthesize the primary transcript for the lac operon at an average elongation rate of 70 nucleotides per second.
