Acids and bases have been used by chemists for centuries, and are among the most fundamental reagents employed in synthetic organic chemistry. This Aldrich product line ranges from BrÃ¸nsted and Lewis... Chemfiles Volume 1 Article 3.
Bases are found in both DNA and RNA. As seen below, they are adenine, cytosine, guanine, thymine, and uracil. They are abbreviated (A, C, G, T, U). Three of the bases (A, G, C) are found in both DNA and RNA. However, uracil (U) is found only in RNA and thymine (T) is found only in DNA.he first three are the same as those found in DNA, but in RNA thymine is replaced by uracil as the base complementary to adenine. This base is also a pyrimidine and is very similar to thymine.
Uracil is found in RNA and binds to adenine via 2 hydrogen bonds, but is replaced by thymine in DNA. Methylation of Uracil produces thymine. Uracil can pair with any of the base pairs depending on arrangement. Despite this, it readily pairs with adenine because the methyl group is repelled into a fixed position. In the uracil and adenine bond, uracil is the hydrogen bond acceptor and the adenine is the donor. When attached to a ribose sugar, the compound is called uridine, a nucleoside. Then, phosphate attaches to uridine to form uridine 5'-monophosphate.
