    Study Notes

    Nucleic Acids

    • DNA and RNA are two types of nucleic acids in living organisms.
    • DNA is the genetic material in most organisms.
    • RNA is the genetic material in some viruses, but mostly acts as a messenger.
    • RNA also has other roles: adapter, structural, and catalytic.
    • Nucleotide structures and their linking into nucleic acid polymers were covered in Class XI.

    DNA Structure and Function

    • This chapter covers DNA structure, replication, transcription, the genetic code, protein synthesis, and regulation.
