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 pineal gland (also called the pineal body or epiphysis) is a small endocrine gland in the brain. It is located near the center of the brain, between the two hemispheres, tucked in a groove where the two rounded thalamic bodies join.It consists of two types of cells 1. parenchymal cells 2. neuroglial cells.he pineal gland (also called the pineal body or epiphysis) is a small endocrine gland in the brain.
