Study Notes
DNA: The Genetic Blueprint
- Deoxyribonucleic acid (DNA) is the genetic material found in virtually all cells.
- In eukaryotic cells, DNA is located within the nucleus, a membrane-bound organelle.
- Prokaryotic cells, lacking a nucleus, store their DNA in a region called the nucleoid.
- Prokaryotic cells are unique in that they do not have membrane-bound organelles.
- True bacteria (eubacteria) and Archaebacteria use DNA as their genetic material.
- The building block of DNA is a nucleotide, composed of a sugar (deoxyribose), a phosphate group, and one of four nitrogenous bases (adenine, guanine, cytosine, or thymine).
- The pairing of adenine (A) with thymine (T) in a DNA molecule is known as complementary base pairing.
- Avery, MacLeod, and McCarty provided evidence confirming DNA as the transforming agent in cells.
- Friedrich Miescher initially called the cellular substance he identified from the nucleus nuclein.
- A gene is a sequence of nucleotides that provides cells with the instructions to synthesize a specific protein or a particular type of RNA.
