Explain DNA fingerprinting
Answers (1)
DNA fingerprinting:
Examining the individual patterns in a person's DNA, DNA fingerprinting is a scientific method of identifying them. Because everyone's DNA code is different—except for identical twins—this approach identifies individuals, finds familial relationships, and helps solve crimes.
The first step is to obtain a DNA sample from something like skin cells, blood, saliva, or hair. Special enzymes then slice the DNA into tiny fragments. These fragments are sorted using gel electrophoresis, a technique that creates a distinctive banding pattern. This form is called a DNA fingerprint.
Often, DNA testing is utilized to solve crimes by linking DNA discovered at the scene to a suspect. Medical research also makes use of it to investigate DNA disorders; paternity tests use it to determine a child's genuine parentage.
Because it performs very effectively and can be relied upon, this approach is among the most crucial instruments in contemporary research. Understanding genetic diseases helps to guarantee justice, strengthen family relationships, and improve health care.
