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.
Located at the base of the brain, the pituitary gland is protected by a bony structure called the sella turcica of the sphenoid bone. Median sagittal through the hypophysis of an adult monkey. Semidiagrammatic.
The pituitary gland situated at the back of the brain is responsible for the creation of many hormones that are related to growth in animals. The amount of each hormone produce is regulated by the hypothalamus, a part of the brain situated next to the pituitary gland.
