遗传指纹分析 DNA profiling

(重定向自DNA profile)

遗传指纹分析Genetic fingerprinting)有时也称为基因标定基因鉴定等,是一种使用通过比较DNA片段来区别不同个体的方法。于1985年,由莱斯特大学的亚历克·杰弗里斯教授发明。

用限制性内切酶消化含短重复串行的DNA,以分析不同个体产生的片段差异。因为它们对每个个体而言都是独一无二的,任何两个个体出现特定的长短的DNA片段,就能用于确定它们间有无共同的遗传来源(如亲子关系)。

Variations of VNTR allele lengths in 6 individuals.
Alec Jeffreys, the pioneer of DNA profiling.
1: A cell sample is taken- usually a cheek swab or blood test

 2: DNA is extracted from sample

 3: Cleavage of DNA by restriction enzyme- the DNA is broken into small fragments

 4: Small fragments are amplified by the Polymerase Chain Reaction- results in many
 more fragments

 5: DNA fragments are separated by electrophoresis

 6: The fragments are transferred to an agar plate

 7: On the Agar Plate specific DNA fragments are bound to a radioactive DNA probe

 8: The Agar Plate is washed free of excess probe

 9: An x-ray film is used to detect a radioactive pattern

 10: The DNA is compared to other DNA samples
CBP chemist reads a DNA profile to determine the origin of a commodity.

DNA profiling (also called DNA fingerprinting, DNA testing, or DNA typing) is a forensic technique used to identify individuals by characteristics of their DNA. A DNA profile is a small set of DNA variations that is very likely to be different in all unrelated individuals, thereby being as unique to individuals as are fingerprints (hence the alternate name for the technique). DNA profiling should not be confused with full genome sequencing. First developed and used in 1985, DNA profiling is used in, for example, parentage testing and criminal investigation, to identify a person or to place a person at a crime scene, techniques which are now employed globally in forensic science to facilitate police detective work and help clarify paternity and immigration disputes.
