Reverse genetics


Reverse genetics is an approach to discovering the function of a gene that proceeds in the opposite direction of so called forward genetic screens that are more usual in classical genetics.

Reverse genetics is an approach to discovering the function of a gene that proceeds oppositely to how such discoveries typically unfold in classical genetics, or in forward genetics.

Reverse genetics has been applied successfully to
plants [examples];
mice [Link];
C. elegans;
and can also be used with the zebrafish.

Reverse genetics
An approach where a cloned gene with an unknown function is used to disrupt the corresponding chromosomal gene to examine the resulting phenotype.

Molecular geneticists often use reverse genetics in which a specific mutation is made in vitro and then introduced into an organism's genome.

Since the protein product of the defective NF1 gene had not been isolated, investigators used the relatively new approach sometimes referred to as reverse genetics or positional cloning.

Reverse genetics. Using linkage analysis and polymorphic markers to isolate a disease gene in the absence of a known metabolic defect, then using the DNA sequence of the cloned gene to predict the amino acid sequence of its encoded protein.
