DNA and Chromosome Structure

Learning Outcomes

  • Discuss the potential implications of mutations at cellular, organismal, and evolutionary levels
    • Describe the structure of DNA and the process of DNA replication.

DNA is a nucleic acid, which is one of the four biological macromolecules that you began learning about in BI211. Recall that nucleic acids are made up of monomers called nucleotides joined together by strong covalent bonds.

All living things store genetic information using nucleic acids: either DNA or a related molecule called RNA. Different organisms have different ways of packaging and storing DNA inside their cells.
