10.2 DNA and RNA are polymers of nucleotides
{"Image DocumentName": "10.2 DNA and RNA are polymers of nucleotides", "Image ImageDescription": "The monomer unit of DNA and RNA is the nucleotide, containing. Nitrogenous base. 5-carbon sugar. Phosphate group. Student Misconceptions and Concerns. 1. If your class has not yet studied Chapter 3, consider assigning module 3.16 on Nucleic Acids before addressing the contents of Chapter Students often confuse the terms nucleic acids, nucleotides, and bases. It helps to note the hierarchy of relationships: nucleic acids consist of long chains of nucleotides (polynucleotides), while nucleotides include nitrogenous bases. Teaching Tips. 1. The descriptions of the discovery of DNA\u2019s structure are a good time to point out that science is a collaborative effort. Watson, Crick, and Wilkins earned Nobel prizes due to their historic conclusions based upon the work of many others (including Griffith, Hershey, Chase, Franklin, and Chargaff). 2. Consider comparing DNA, RNA, and proteins to a train (polymer). DNA and RNA are like a train of various lengths and combinations of four types of train cars (monomers). Proteins are also trains of various lengths but made of a combination of 20 types of train cars.
