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).

It is a glycoprotein hormone, synthesized and secreted by thyrotrope cells in the anterior pituitary gland, that regulates the endocrine function of the thyroid gland. thyroxine: A hormone (an iodine derivative of tyrosine), produced by the thyroid gland, that regulates cell metabolism and growth.
