As the name suggests, thymine may be derived by methylation of uracil at the 5th carbon. In RNA, thymine is replaced with uracil in most cases. In DNA, thymine (T) binds to adenine (A) via two hydrogen bonds, thus stabilizing the nucleic acid structures.Thymine combined with deoxyribose creates the nucleoside deoxythymidine, which is synonymous with the term thymidine.hymine is also known as 5-methyluracil, a pyrimidine nucleobase. In RNA, thymine is replaced by the nucleobase uracil. Thymine was first isolated (from calves' thymus glands) in 1893 by Albrecht Kossel and Albert Neumann.
In vertebrate anatomy, the pituitary gland, or hypophysis, is an endocrine gland about the size of a pea and weighing 0.5 grams (0.018 oz) in humans. It is a protrusion off the bottom of the hypothalamus at the base of the brain.
Yes, it is basically the base of the brain; it is where the brain starts. The brain stem extends from the spinal cord into the brain and is the oldest (most primitive) part ofâ¦ the brain. Over time, the brain has developed on top of the brain stem to come to what it is today (in modern humans).
