The first step in gene expression would be the transcription of RNA. What happens here is that a part of the DNA is being replicated into the RNA through an enzyme. Therefore, what happens first during transcription is that, the RNA polymerase reaches the start of a gene. The answer would be B.
Answer:
Operons can be used to coordinate the expression of multiple proteins in combination in the prokaryotes. An operon is a fundamental unit of DNA that transcribes, translates, or splices an array of genes under the guidance of a single operator and promoter.
The expression of genes can take place in combination or not at all. The regulation of operon can either be positive or negative due to repression or induction.
