If the transcriptional termination signal for gene X is deleted in E. coli, the resulting protein X made from that RNA will be: a) longer because the termination signal has been removed b) shorter because information to necessary to synthesize that protein will be missing c) not changed, protein X of the appropriate length will still be made

What is the role of the protein
encoded by the lacZ gene?
What is the role of the protein encoded by the lacZ gene? The lacZ gene encodes an enzyme that converts lactose to allolactose, and the lacZ gene O O O O encodes an enzyme that converts lactose to glucose and galactose. The lacZ gene encodes an enzyme that permits lactose to enter the bacterial cell. The lacZ gene encodes an enzyme that converts lactose to glucose and galactose....
Identify and describe the role of two components in the transformation of E. coli in this experiement,
The gene encoding protein Bog in E. coli has been changed by a point mutation in its open reading frame. Originally the gene encoded a 108 amino acid long functioning protein whose amino acid composition favored nonpolar and negatively charged amino acids. After the mutation it encodes a 110 amino acid long non-functioning protein that is now rich in polar uncharged amino acids and positively charged amino acids. Which mutation scenario best explains this observation. A) A frame-shift caused by...
1) What does beta lactamase do, and how is that helpful in selecting bacteria that contain your plasmid of interest (in this case, pUC19)? 2) (6 points) What protein fragment does the gene lacZ alpha encode for? a. When this peptide is expressed in E. coli DHSq, it combines with an E.coli expressed peptide to make a functional protein. What is this E. coli encoded peptide called? b. What is the biological role of the complete protein that is made...
10. Describe and diagram the mechanism of regulating gene expression utilized for the E. coli trp operon. Compare and contrast this to the general strategy utilized for the lac operon.
Answer the following questions: a) What is special about the E coli BL21(DE3)pLysS cells used for gene expression? b) In what structural form is the expressed gdhA gene synthesized in the E coli host cells? c) What physical attributes of SDS-PAGE gels allow the separation and molecular weight determination of polypeptides? d) Given the size of the gdhA gene of ~1362 bp, what is the theoretical size of the expressed protein? e) Does your answer from (d) agree with the...
consider a strain of E. coli that has a mutation in the gene encoding the IIA protein of the phosphotransferase system. The transport and phosphorylation of glucose is not affected by this mutation and the phosphate group is transferred to glucose as in the wildtype strain. Also, the interaction between the mutant IIA protein and Lacy is not affected by the mutation. However, the mutation does affect the IIA protein's interactions with adenylate cyclase and the phosphorylated form of the...
