Instructions in the DNA are first transcribed to RNA and the RNA is transported to the ribosome in the cytoplasm.
<h3>Transcription</h3>
Transcription is a process whereby the genetic instructions in the DNA of organisms are transcribed to RNA in the nucleus.
After transcription, the RNA which now carries the genetic codes is transported to the cytoplasm where it gets attached to the ribosome before the genetic codes are translated to their respective amino acids.

Answer: both parathyroid hormone and calcitrol.
Explanation:
In the body calcium homeostasis, which is generally defined as the maintenance of specific internal conditions, is mediated by the endocrine system through hormonal control; hormones are usually specialized signal molecules derived from lipids or amino acids. This regulates the calcium flux between the bloodstream and the bone; and the hormones responsible, change the ratio of osteoclast activity to osteoblast activity -osteoblasts build bone while osteoclasts breakdown or degrade bone.
Hormones responsible include calcitonin (from special parafollicular cells in the thyroid gland), cacitrol (activated vitamin D) and the parathyroid hormone (from the parathyroid glands). These affect the absorption of calcium from the gut, or kidney reabsorption; both parathyroid hormone and calcitrol act by causing the release of calcium ions into the bloodstream as the bone is degraded by osteoclasts.
The study of the human body would be anatomy.
