DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) are composed of two different classes of nitrogen-containing bases: the purines and pyrimidines. The most commonly occurring purines in DNA are adenine and guanine: Figure 1.2.1: Purines. The most commonly occurring pyrimidines in DNA are cytosine and thymine: Figure 1.2.2: Pyramidines

Learn about the basic structure, function, and diversity of RNA molecules, and how they differ from DNA. Explore the history and discoveries of RNA research, from the RNA Tie Club to the Nobel Prize winners.
23 sie 2020 · Three differences between DNA and RNA are that DNA uses the base thymine while RNA uses uracil, DNA uses the sugar deoxyribose while RNA uses ribose, and usually DNA is double-stranded and RNA is single-stranded.
31 paź 2023 · The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the genetic material found in all living organisms, ranging from single-celled bacteria to multicellular mammals. It is found in the nucleus of eukaryotes and in the chloroplasts and mitochondria.
