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).

Thyroid cells are the only cells in the body which can absorb iodine.
The thyroid gland has 2 main types of cells: 1  Follicular cells use iodine from the blood to make thyroid hormones, which help regulate a personâs metabolism. 2  C cells (also called parafollicular cells) make calcitonin, a hormone that helps control how the body uses calcium.ther, less common cells in the thyroid gland include immune system cells (lymphocytes) and supportive (stromal) cells. Different cancers develop from each kind of cell. The differences are important because they affect how serious the cancer is and what type of treatment is needed.
