The nitrogen containing base that is found only in RNA is uracil. What are the names of the nucleotides found in DNA and RNA?   In DNA, the four bases are: adenine, guanine, thymine, and cytosine. Each base is attached is attached to a sugar (deoxyribose) to form a nucleoside. Respectively, tâ¦hese are: adenosine, guanosine, thymidine, and cytidine.
RNA (ribonucleic acid) molecules differ from DNA molecules in several ways. RNA molecules are single-stranded, and their nucleotides contain ribose rather than deoxyribose sugar. Like DNA, RNA nucleotides each contain one of four organic bases, but whereas adenine, cytosine, and guanine nucleotides occur in both DNA and RNA, thymine nucleotides are found only in DNA. In place of thymine nucleotides, RNA molecules contain uracil nucleotides. The first step in the delivery of information from the nucleus to the cytoplasm is the synthesis of a type of RNA called messenger RNA (mRNA). In messenger RNA synthesis, RNA nucleotides form complementary base pairs with a section of a strand of DNA that encodes a particular protein.
