Doctors have not been able to find a mutation in the rna polymerase gene. Why is that?

Expert Solution

Answer:

Explanation: RNA polymerase gene encodes RNA polymerase enzyme and is responsible for transcribing all RNA molecules (mRNA, tRNA, rRNA) from DNA by the process of transcription. In turn, proteins are translated from these RNA molecules with amino acids pool. Therefore, all the proteins and enzymes synthesis is dependent primarily on transcription which occurs with these significant and crucial enzymes. If there is a mutation in this enzyme and the mutation are somehow lethal or mutation decreases the speed of the enzyme or decreases its affinity to substrates. It will prove fatal and the organism will die. This is the reason why this gene is conserved because it wouldn’t like to take risk at the cost of organism’s death. In conclusion, the importance, significance and the critical and crucial role played by RNA polymerase reserves its gene sequence to keep its functionality intact.

Application questions Can a protein be translated if a cell is defective for RNA polymerase? Why or why not? What would happen if the aminoacyl tRNA synthetase specific for a tRNA carrying lysine were missing during translation? How would this deficiency affect transcription? What sequences are in DNA that are not found in the processed mRNA? What are the sequences that are in processed mRNA that are translated into polypeptide?

Consider a colony of E. coli cells that have a mutation in the lac I gene, resulting in a LacR protein that cannot bind to allolactose. Describe the effect that this mutation will have on the lac operon in terms of βgal protein levels when the cells are grown in media containing lactose but no glucose. Explain your reasoning.
