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.
Thymine versus uracil. Our genetic information is stored in the form of DNA, using a four-letter alphabet. The four âlettersâ correspond to the four chemical bases that each building block of DNA â called a nucleotide â can have: adenine (A), thymine (T), cytosine (C) and guanine (G; see Figure 1).
