Question

All are applications of DNA fingerprinting except
A. In forensic science
B. To amplify minisatellite
C. Diagnosis of inherited disorders
D. Paternity testing

Answer 1

DNA fingerprinting is used to analyze the DNA sequence. It is used to detect criminals, inherited disorders and also genetic parents. Amplification of minisatellites can be done by the process of polymerase chain reaction.

Complete answer:
DNA fingerprinting is the laboratory technique used to detect similarities between DNA. This technique was developed in 1984 by British geneticist Alec Jeffrey. A DNA sample collected from a crime scene is compared with a DNA sample from a suspect. If the match between DNA profiles found, then the suspects must be present at the crime scene. It has a great importance in forensic science. It is also used to establish paternity. DNA is located within the nucleus of cells. Every individual has its specific DNA sequence. The specific sequence in DNA called variable number repeats. DNA fingerprinting is called DNA typing, DNA profiling, genetic fingerprinting, genotyping, or identity testing. Parents and children have fewer chances of differences in their DNA, so their DNA is checked to find the identity of real parents. Inherited disorders are inherited from parents to the offspring. There is a possibility that traces of disorder can be found in the DNA of parents as well. Inherited disorders are present on DNA. DNA fingerprinting is used to analyze the DNA samples. From the above information we have found that all the above mentioned processes are the application of DNA fingerprinting except amplification of minisatellites of DNA.

Hence, the correct answer is option C.

Note: DNA is isolated from the sample. Fragments are formed by the process of electrophoresis. These fragments run parallely and analysis of every sample is done. DNA fingerprinting is the analysis process not the amplification. The amplification of specific DNA sequence can be done by the process of PCR(polymerase chain reaction).
