what would happen to transcription in e coli if the genes ending the rna polymerase beta subunits were mutated
Homework Answers
The RNA polymerase is made up of four subunits, Two 
, one 
, and one 
.
,
- Helps in RNA assembly and helping
- Helps in initiation and elongation
-
Helps in the Binding of complex and opening DNA.
If there is a mutation in RNA polymerase beta subunits then RNA will not be transcribed as the core complex cannot add the complementary nucleotide to the RNA that results in no transcription or no synthesis of RNA.
Please write to me if you need more help.

Why does E. coli have several different sigma factors? A.They allow RNA polymerase I, RNA polymerase II and RNA polymerase III to bind to different promoters. B.They allow the different subunits of the RNA polymerase holoenzyme to bind to each other. C.They are redundant in case one is mutated. They all perform the same function. D.One is needed to transcribe mRNA. A second is needed to transcribe tRNA. And a third is needed to transcribe rRNA. E.They are used if...

Calculate the minimum length of time required for E. coli RNA polymerase to synthesize an mRNA that encodes a 100 kDa protein. The molecular weight of an amino acid is approximately 110 Da. E. coli RNA polymerase has a transcription rate of approximately 50 nucleotides per second. Round your answer to the nearest whole number.

Compare the activities of E. coli DNA polymerase III and RNA polymerase by describing the following properties of each: DNAP III (Replication) RNAP (Transcription) Substrate(s) i.e. what does the enzyme link together Name for the site of enzyme binding Is a primer required? What serves as template(s)? End product Direction of polymerization
Which of the following is true for transcription in E. coli, but not for transcription in...
Which of the following is true for transcription in E. coli, but not for transcription in humans? a. Transcription requires RNA polymerase to add nucleoside triphosphates to the 3' end of the growing transcript (RNA). b. Transcription does not require primers during initiation or elongation. c. Transcription requires promoters, which have mostly adenines and thymines. d. Transcription produces polycistronic mRNA that includes several coding regions within one transcription unit.

16) What would happen if a mutation occurred in E. Coli that eliminated the production of the protein sigma? A) Ribosomes would no longer be able to participate in translation B) mRNA transcripts would no longer be produced C) Amino Acids could no longer be connected to one another via peptide bonds D) Introns would no longer be spliced out of MRNAs E) mRNA transcripts could not dissociate from the RNA polymerase

Why are related genes transcribed together? Why is transcription regulated? RNA Polymerase does not have proofreading mechanism and the error rate is 1 per 104~105, why is fidelity not as important as during DNA replication? Which RNAs are not translated to proteins?

Part
A
The sigma (?) subunit binds to the core RNA polymerase
enzyme. The function of this sigma factor is to recognize and bind
to the promoter of a gene so that transcription can be initiated.
The closeup shows the secondary structure of the sigma (?)
subunit, which consists of four domains. Identify the domains
labeled 1-3.
