Question

In an essay of between 100-150 words, explain the events that occur during transcription initiation in prokaryotes. You may wish to include the structure of a gene promoter in your summary. You must be thorough enough to use up 100-150 words, but not too verbose to go beyond that word limit.

Answer 1

Prokaryatic transcription formation of RNA from the their genome are called transcription. In Prokaryotic system single polymerase perform all the function of transcription. The mRNA molecule /sequence are derived from the coding region of the DNA sequence.
