Question

Who found DNA testing?

Answer 1

Hint: Nucleic acids are organic materials found in all organisms that take the form of DNA or RNA. These nucleic acids are created by combining nitrogenous bases, sugar molecules, and phosphate groups that are linked together in a series of bonds. The DNA structure defines our body's basic genetic makeup. In fact, it defines nearly all of life on Earth's genetic makeup.

Complete answer:
Satellite DNA regions are stretches of repetitive DNA that do not encode for any particular protein. These non-coding sequences constitute a significant portion of the human DNA profile. They exhibit a high level of polymorphism and serve as the foundation for DNA fingerprinting. These genes exhibit a high level of polymorphism in all types of tissues, making them extremely useful in forensic studies.

Genetic testing, also known as DNA testing, is used to detect changes in the sequence of DNA or the structure of chromosomes. Measurement of the results of genetic changes, such as RNA analysis as an output of gene expression, or biochemical analysis to measure specific protein output, can also be included in genetic testing.

Sir Alec John Jeffreys (born 9 January 1950) is a British geneticist best known for developing techniques for genetic fingerprinting and DNA profiling, which are now used in forensic science around the world to aid police detective work and resolve paternity and immigration disputes.

Thus, Sir Alec John Jeffreys found DNA testing.

Note: Most genetic tests have very low physical risks, particularly those that require only a blood sample or a buccal smear (a procedure that samples cells from the inside surface of the cheek). Because prenatal testing requires a sample of amniotic fluid or tissue from a pregnant woman, there is a small but not insignificant risk of miscarriage.
