Summary Introduction

Introduction:

Restriction enzyme finds the specific sequence of interest and cut the DNA sequence. It results in the fragments of specific DNA sequence.

Answer to Problem 1MCQ

Correct answer:

GAATTC occurs three times in the given sequence. Thus, the restriction enzyme will cut three times, which will produce four fragments. Hence, the correct answer is option c.

Explanation of Solution

Reason for correct answer:

Option c. is given as, “Four.”

Restriction enzyme will cut the sequence where it will find the GAATTC and this sequence is present three times in the given sequence; TGAG/AATTCAACTG/AATTCAAATTCG/AATTCTTAGC. Hence, it will produce four fragments of the given sequence.

Reason for incorrect answer:

Option a. is given as, “Two.”

GAATTC is present three times in the sequence of interest, which will generate four fragments, not two. Hence, option a. is incorrect.

Option b. is given as, “Three.”

When restriction enzyme will cut the sequence three times, then four fragments will be produced. Hence, option b. is incorrect.

Option d. is given as, “Five.”

GAATTC occurs three times in the given sequence; thus, it will generate four fragments, not five. Hence, option d. is incorrect.

Hence, the options a., b., and d. are incorrect.

Conclusion

GAATTC is present three times in the sequence of interest. The restriction enzyme will cut the sequence three times and will generate four fragments. Thus, the correct option is c.

The diagram below illustrates a quorum sensing pathway from Staphylococcus aureus. Please answer the following questions. 1. Autoinduction is part of the quorum sensing system. Which promoter (P2 or P3) is critical for autoinduction? 2)This staphylococcus aureus grows on human wounds, causing severe infections. You would like to start a clinical trial to treat these wound infections. Please describe: a) What molecule do you recommend for the trial. Why? b) Your trial requires that Staphylococcus aureus be isolated from the wound and submitted to genome sequencing before admittance. Why? What are you testing for?  3) If a mutation arises where the Promoter P3 is constitutively active, how would that influence sensitivity to AIP? Please explain your rationale. 4) This pathway is sensitive to bacterial cell density. Describe two separate mutation that would render the pathway active independent of cell density. Briefly explain your rationale. Mutation 1 Mutation 2
