DNA fingerprinting is done for ___________________.
-
Crime investigation
-
Detection of Hair colour
-
Gender of the offspring
-
All of the above
DNA profiling or fingerprinting is used in, 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. Therefore, the correct answer is option A.
Science connected with identification in criminal activities and law is
-
Medical transcription
-
Pathology
-
Forensic science
-
Computational biology
Forensic science is the application of science to the law. In criminal cases, forensic scientists are often involved in the search for an examination of physical traces which might be useful for establishing or excluding an association between someone suspected of committing a crime and the scene of the crime or victim.
The technique used in correct identification of individuals and relations is
-
Forensic science
-
Human reproductive biology
-
Microbiology

DNA fingerprinting
DNA fingerprinting is a method used to identify an individual from a sample of DNA by looking at unique patterns in their DNA. DNA is present in blood, hair, semen and various other body cells which can be used to isolate DNA for the process of DNA fingerprinting.
The PCR technique was invented by
-
Karry Mullis
-
Cohen
-
Boyer
-
Sanger
Best method to determine paternity is
-
Protein analysis

DNA finger printing
About 3% or so of the human genome has highly repetitive sequences termed as simple-sequence DNA or satellite DNA that are repeated in multiples per cell and generate tandem repeats. This DNA polymorphism is revealed during DNA finger printing in the identification of paternity since it is very remote possibility to have two individuals same repeats of satellite DNA throughout the genome except they share a biological relationship. This is because a child gets half DNA from father and half from the mother. Restriction enzymes of genome produce the restriction fragments length polymorphisms, or RFLPs depending on the location of restriction sites which are then sorted by gel electrophoresis followed by southern blotting. The blots of parental and child genome are compared for sequence homology using radioactive probes; option D is correct.
Genetic counsellors can identify heterozygous individuals by
-
Height of individuals
-
Colour of individuals
-
Screening procedures
-
All of these

-
All the above
A - The DNA finger print is the same for every cell, tissue and organ of a person.
R - DNA fingerprint is used for treatment of inherited disorders like Huntigton's disease, Alzheimer's and Sickle cell anemia.
-
A and R both are correct. R is explanation of A
-
A and R both are correct but R is not explanation of A
-
A is correct and R is wrong
-
A is wrong and R is correct
DNA fingerprint is the unique DNA pattern of each individual. It is the same for every cell, tissue and organ of an individual. DNA fingerprinting is a method used to identify an individual on the basis of unique patterns of its DNA. It is used in the diagnosis of inherited disorders like cystic fibrosis, Alzheimer's disease, Huntington's disease, Sickle cell anemia.
