Summary Introduction

To determine: The inference from the given experiment.

Introduction: In 1962, F. Chapeville and others reported an experiment in which they isolated radioactive C14-cysteinyl-tRNACys. They further removed the sulfur group from the cysteine and created alanyl-tRNACys. When alanyl-tRNACys was added to a synthetic mRNA, a polypeptide chain was synthesized containing alanine.

Expert Solution & Answer
Check Mark

Explanation of Solution

As per the given information, a polypeptide chain was synthesized containing alanine. This occurred after adding radioactively labeled alanyl-tRNACys to a synthetic mRNA. From the given experiment, one can conclude that the amino acid is not involved in recognition of the codon.

Conclusion

Thus, from the given experiment, one can conclude that the amino acid is not involved in recognition of the codon.

Molecular Biology Please help with question. thank you You are studying the expression of the lac operon. You have isolated mutants as described below. In the presence of glucose, explain/describe what would happen, for each mutant, to the expression of the lac operon when you add lactose AND what would happen when the bacteria has used up all of the lactose (if the mutant is able to use lactose).5. Mutations in the lac operator that strengthen the binding of the lac repressor 200 fold 6. Mutations in the promoter that prevent binding of RNA polymerase 7. Mutations in CRP/CAP protein that prevent binding of cAMP8. Mutations in sigma factor that prevent binding of sigma to core RNA polymerase
Molecular Biology Please help and there is an attached image. Thank you. A bacteria has a gene whose protein/enzyme product is involved with the synthesis of a lipid necessary for the synthesis of the cell membrane. Expression of this gene requires the binding of a protein (called ACT) to a control sequence (called INC) next to the promoter. A. Is the expression/regulation of this gene an example of induction or repression?Please explain:B. Is this expression/regulation an example of positive or negative control?C. When the lipid is supplied in the media, the expression of the enzyme is turned off.Describe one likely mechanism for how this “turn off” is accomplished.
Molecular Biology Please help. Thank you. Discuss/define the following:(a) poly A polymerase (b) trans-splicing (c) operon
