Chapter 20, Problem 1TY
Summary Introduction

Introduction: Vector is a key material that is used in the process of gene cloning. It acts as a carrier of the DNA segment that has to be cloned. When this vector is introduced into a living cell, it replicates with the DNA it carries and produces many identical copies of the inserted gene.

Answer to Problem 1TY

Correct answer: The vectors used to clone genes were derived originally from plasmids or viruses. Hence, the correct answer is option e.

Explanation of Solution

Reason for correct answer:

The vectors commonly used in the gene cloning experiments are derived from plasmids or viruses. The plasmids contain unique sites into which the gene of interest can be easily inserted. Viruses can also be used as vectors to carry the pieces of DNA. This is because when a gene of interest is inserted into a viral vector, the gene gets replicated along with the replication of the viral DNA.

Option e. is given as “b and c only”.

Plasmids are small, circular pieces of DNA that are naturally found in many strains of bacteria. The plasmids exist independently of the bacterial chromosome. The plasmids can be genetically engineered for the effective use in cloning experiments. The viral vectors infect living cells and propagate themselves by taking control of the host cell’s metabolic machinery. Hence, the correct answer is option e.

Reasons for incorrect answer:

Option a. is given as, “proteins”.

The vectors are not derived from proteins. Hence, option a. is incorrect.

Option b. is given as, “plasmids”.

The vectors are derived not only from plasmids but also from the viruses. Hence, option b. is incomplete.

Option c. is given as, “viruses”.

The vectors are derived not only from viruses but also from plasmids. Hence, option c. is incomplete.

Option d. is given as, “all of the above”.

The vectors are derived from plasmid or viruses, but not from proteins. Hence, option d. is incorrect.

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

Conclusion

Hence, the vectors used to clone the genes are derived originally from viruses or plasmids.

Preoperative Diagnosis: Torn medial meniscus, left knee Postoperative Diagnosis: Combination horizontal cleavage tear/flap tear, posterior horn, medial meniscus, left knee. Operation: Arthroscopic subtotal medial meniscectomy, left knee Anesthetic: General endotracheal Description of Procedure: The patient was placed on the operating table in the supine position and general endotracheal anesthesia was administered. After an adequate level of anesthesia was achieved, the patient's left lower extremity was prepped with Betadine scrubbing solution, then draped in a sterile manner. Several sites were then infiltrated with 1% Xylocaine solution with Epinephrine to help control bleeding from stab wounds to be made at these sites. These stab wounds were made anterolaterally at the level of the superior pole of the patella for insertion of an irrigation catheter into the suprapatellar pouch area, anterolaterally at the level of the joint line for insertion of the scope and anteromedially at…
