An organism’s genome contains many variable number tandem repeats (VNTRs). The probability of two individuals having the same VNTRs is very low. The technique of genetic fingerprinting in analysing DNA fragments that have been cloned by PCR, and its use in determining genetic relationships and in determining the genetic variability within a population. The use of genetic fingerprinting in forensic science. Students should be able to: Explain the biological principles that underpin genetic fingerprinting techniques and Interpret data showing the results of gel electrophoresis to separate DNA fragments. ★ CIE Specification Reference: - 19.1 Principles of genetic technology. d) describe and explain how gel electrophoresis is used to analyse nucleic acids, and to distinguish between the alleles of a gene (limited to the separation of DNA fragments cut with restriction endonucleases). ★ Edexcel (Biology A – Salters-Nuffield) Specification Reference: - Topic 6: Immunity, Infection and Forensics. 6.3 Know how DNA profiling is used for identification and determining genetic relationships between organisms (plants and animals). Use gel electrophoresis to separate DNA fragments of different length. ★ Edexcel (Biology B) Specification Reference: - Topic 7: Modern Genetics. 7.1 Using gene sequencing. Understand what is meant by the term genome. Understand how PCR can be used to amplify DNA samples, and how these samples can be used in forensic science, to identify criminals and to test paternity, using DNA profiling. ★ OCR (Biology A) Specification Reference: - 6.1.3 Manipulating genomes. (c) the principles of DNA profiling and its uses. To include forensics and analysis of disease risk. (d) the principles of the polymerase chain reaction (PCR) and its application in DNA analysis (e) the principles and uses of e
