The sugar in DNA is 2-deoxyribose, which is a pentose (five-carbon) sugar. The sugars are joined together by phosphate groups that form phosphodiester bonds between the third and fifth carbon atoms of adjacent sugar rings. These asymmetric bonds mean a strand of DNA has a direction.
At other times it may migrate too far and ends up in the chest (this is also rare). The function of the thyroid gland is to take iodine, found in many foods, and convert it into thyroid hormones: thyroxine (T4) and triiodothyronine (T3). Thyroid cells are the only cells in the body which can absorb iodine.These cells combine iodine and the amino acid tyrosine to make T3 and T4.t other times it may migrate too far and ends up in the chest (this is also rare).

Functions of the thyroid gland. The thyroid plays an important role in regulating the body's metabolism. Virtually every tissue in the body is affected or regulated by thyroid hormone. It regulates our metabolism, brain development and function, skin, hair, eyes, heart, and intestine function.he thyroid hormones enter into tissues and regulate how those tissues produce or do not produce certain proteins. The thyroid function is controlled by the pituitary, which sits at the base of the brain. The pituitary is controlled by a region in the brain called the hypothalamus.
