Summary Introduction

To explain: The reason why primary rRNA transcripts are present in wild-type E. coli.

Introduction: Transcription is a process by which the nucleotide sequences of a gene are transcribed into the mRNA sequences that code for proteins. This marks the beginning of gene expression. In all species, transcription initiates through binding of RNA polymerase enzyme at the promoter region (beginning of gene). The sequence downstream to the promoter sequence is known as the transcription unit. This sequence is transcribed into the mRNA and forms the primary transcript.
