Which statements about insulin are correct?

$\left(\mathrm{i}\right)$ Raised blood glucose level triggers cells of Islets of Langerhans to release insulin.

$\left(\mathrm{ii}\right)$ Decreased blood glucose level triggers cells of Islets of Langerhans to release insulin.

$\left(\mathrm{iii}\right)$ The binding of insulin to receptors on the cell's membrane activates the transport of glucose and protein.

$\left(\mathrm{iv}\right)$ Without insulin, glucose builds up in the blood and the cells are starved of their energy source.

Insulin extracted and purified from the pancreas of cattle and pigs function well in the human body because

Insulin obtained from genetically engineered organism is more useful because

In somatic cell therapy, gene defects are corrected by

Gene therapy involves

Assertion$\left(\mathrm{A}\right)$: Mice are a preferred choice for transgenic experiments.

Reason $\left(\mathrm{R}\right)$: Mice have short generation time.

Which of the following pairs is $\mathrm{NOT}$ correctly matched$?$
