Control of gene expression official content key terms

DNA profiling

A technique used to identify individuals by examining their unique DNA patterns.

Restriction fragment length polymorphism (RFLP)

A method used in genetic fingerprinting that analyzes variations in DNA fragment lengths after restriction enzyme digestion.

Gel electrophoresis

A laboratory method used to separate DNA fragments according to their size by applying an electric field to a gel matrix.

DNA fingerprinting

A technique used to identify individuals based on unique patterns in their DNA, often used in forensic science and paternity testing.

DNA profiling

The process of determining an individual's DNA characteristics for identification purposes.

Allele

Different forms of a gene that can exist at a specific locus on a chromosome.

Restriction fragment length polymorphism (RFLP)

Variation in DNA fragment lengths produced by restriction enzyme digestion, used as a basis for DNA fingerprinting.

Gel electrophoresis

Method of separating DNA fragments by size using an electric field; essential for visualising DNA fingerprints.
