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.

The pineal gland is situated in the middle of the human brain and is the major site of the bodyâs melatonin production. Computer artwork of a sectioned human brain in side view, showing the pineal gland (highlighted). Front of the brain is at left. The pineal gland is situated deep within the brain, just below the back of the corpus callosum. Pineal body; epiphysis cerebri; epiphysis.
