Recombinant DNA technology can be most accurately defined as the deliberate modification of the genome of an organism for practical purposes. It involves joining together of DNA molecules from two different species that are inserted into a host organism to yield new valuable genetic combinations. The technique may be used to identify, map and sequence genes and also to determine function.
400x. Total magnifaction = Eyepiece magnifaction × Objective magnification.
Answer: Kidneys, intestine and skeletal system
Explanation:
Parathyroid hormone is the hormone that is responsible for regulation of the calcium levels in the extracellular fluid in the body.
It exerts influence over the skeletal system to reabsorb the calcium by the oesteoclasts. It causes the reabsorption of the calcium by the small intestine. It also prevents the excretion of calcium through urine by reabsorption by renal tubules.
