Gurumayum Suraj Sharma THEATTENUATOR Deletion of a sequence between the operator and TrpE gene coding region resulted in an increase in both basal and activated (derepressed) levels of transcription. Site termed ATTENUATOR & lies towards end of transcribed.

Transcription in Prokaryotes: The process of synthesis of RNA by copying the template strand of DNA is called transcription. During replication entire genome is copied but in transcription only the selected portion of genome is copied. The enzyme involved in transcription is RNA polymerase. Unlike DNA polymerase it can initiate transcription by itself, it does not require primase.

transcription complex. The prokaryotic promoter contains only three types of promoter elements. The less involvement of promoter elements in prokaryotes is the main reason why their transcription process is less sophisticated when compared with eukaryotic transcription that involves a higher number of promoter sequences.

Eukaryotic vs. Prokaryotic genes Like in prokaryotes, Eukaryotic genes are regions of DNA that act as templates for the production of RNA by RNA polymerases Recall Prokaryotic transcription: – Transcription factors bind to specific DNA sequences upstream of the start of operons, or sets of related genes.

2. It is a bacterial transcription initiation factor that enables specific binding of RNA polymerase to gene promoters. 3. The specific sigma factor used to initiate transcription of a given gene will vary. It depends on following two factors: a) On gene itself b) On the environmental signals needed to initiate transcription of that gene. 4.

Transcription Proceeds Through 3 Steps • Transcription factors & RNA polymerase recognize & bind the promoter • DNA adjacent to the promoter is denatured forming the open promoter complex Initiation Elongation • RNA polymerase moves along the DNA in synthesizing a RNA transcript. Synthesis is 5’→3’– Only 1 strand of DNA is read as ...

Most prokaryotic genes are regulated in units called operons (Jacob and Monod, 1960) Operon: a coordinated unit of gene expression consisting of one or more related genes and the operator and promoter sequences that regulate their transcription. The mRNAs thus produced are “polycistronic’—multiple genes on a single transcript.

transcription and translation • During attenuation, transcription actually begins but it is terminated before the entire mRNA is made – A segment of DNA, termed the attenuator, is important in facilitating this termination – In the case of the trp operon, transcription terminates shortly past the trpL region (Figure 14.13c)
