Nucleic Acids
Macromolecules that carry genetic information and instructions for making proteins.
DNA
Deoxyribonucleic acid; a storage molecule for genetic information that has a double helix structure.
RNA
Ribonucleic acid; a single-strand structure involved in carrying information from DNA to ribosomes.
Nucleotide
The building block of DNA, consisting of a phosphate, a nitrogen base, and a sugar.
Transformation
Genetic alteration of a cell's DNA due to its surroundings.
Griffith's Experiment
Showed that DNA can transform non-harmful bacteria into harmful ones.
Hershey-Chase Experiment
Demonstrated that the genetic material of a bacteriophage is DNA, not protein.
Chargaff's Rules
In double-stranded DNA, A=T and G=C; this ratio is key to understanding DNA structure.
Watson and Crick
Scientists who proposed the double helix model of DNA, utilizing Rosalind Franklin's x-ray data.
Rosalind Franklin
Scientist who conducted x-ray experiments leading to the discovery of DNA's double helix structure.
