A cloning vector is a naked DNA that can be maintained and into which a foreign DNA can be inserted. A vector needs to be small in size, have restriction sites for endonuclease enzymes and the ability to multiply and express itself at a high rate, without disrupting the host cells machinery. Perfect cloning vectors are DNA molecules from viruses, plasmids and bacterial species such as E.Coli.

Explanation:
Hypothyroidism is a condition caused due to the low amount of production of thyroxine hormone from the thyroid gland.

In the given condition, the thyroxine although lower down the metabolic rate but it is not involved with increased pulse rate, a gain of the weight but not tachycardia. The muscle cramping is caused by the hypocalcemia.
Since the low thyroxine level show response by having dry, sparse hair and intolerance to cold, therefore, option-1 is the correct answer.
