Term
genetic marker
Definition
(1) In gene cloning, a gene of identifiable phenotype that indicates the presence of another gene, DNA segment, or chromosome fragment. (2) In general, a DNA sequence such as a single nucleotide polymorphism whose presence is correlated with the presence of other linked genes on that chromo
Term
transforming principle
Definition
An early term for the as yet unidentified chemical substance responsible for bacterial tranformation
Term
transfection
Definition
 Insertion of recombinant DNA into animal cells.
Term
Griffith's Genetic Transformation Experiment
Definition
Griffith’s experiments demonstrated that something in the virulent S strain of pneumococcus could transform nonvirulent R strain bacteria into a lethal form, even when the S strain bacteria had been killed by high temperatures.
Term
Genetic Transformation by DNA
Definition
Genetic Transformation by DNA Experiments by Avery, MacLeod, and McCarty showed that DNA from the virulent S strain of pneumococcus was responsible for the transformation in Griffith’s experiments 
Term
The Hershey-Chase Experiment
Definition
When bacterial cells were infected with radioactively labeled T2 bacteriophage, only labeled DNA was found in the bacteria. After centrifuging the culture to make the bacteria form a pellet, the labeled protein remained in the supernatant. This showed that DNA, not protein, is the genetic material.
Term
Transfection in Eukaryotic Cells
Definition
he use of a marker gene shows that mammalian cells can be genetically transformed by DNA. Usually, the marker gene is carried by a larger molecule (a virus or a small chromosome).
