In November 2008, Anthony Curcio was arrested for masterminding one of the most elaborately planned armored car heists in history. DNA evidence linked Curcio to the crime. [122] In March 2009, Sean Hodgson—convicted of 1979 killing of Teresa De Simone, 22, in her car in Southampton—was released after tests proved DNA from the scene was not ...
1952: an X-ray diffraction image of DNA was taken by Raymond Gosling in May 1952, a student supervised by Rosalind Franklin. [30] 1953: DNA structure is resolved to be a double helix by James Watson, Francis Crick and Maurice Wilkins. [31] 1955: Alexander R. Todd determined the chemical makeup of nitrogenous bases.
Using these x-rays and information already known about the chemistry of DNA, James D. Watson and Francis Crick demonstrated the molecular structure of DNA in 1953. [25] [26] Together, these discoveries established the central dogma of molecular biology, which states that proteins are translated from RNA which is transcribed by
Genetic testing, also known as DNA testing, is used to identify changes in DNA sequence or chromosome structure. Genetic testing can also include measuring the results of genetic changes, such as RNA analysis as an output of gene expression , or through biochemical analysis to measure specific protein output.

Ancient DNA (aDNA) is DNA isolated from ancient sources (typically specimens, but also environmental DNA). [ 1 ] [ 2 ] Due to degradation processes (including cross-linking , deamination and fragmentation ) [ 3 ] ancient DNA is more degraded in comparison with contemporary genetic material. [ 4 ]
Now, scientists have used ancient DNA collected from the casts that have been made to better understand the Pompeii residents and their origins. What they found alters history that’s been ...
DNA contains the genetic information that allows all forms of life to function, grow and reproduce. However, it is unclear how long in the 4-billion-year history of life DNA has performed this function, as it has been proposed that the earliest forms of life may have used RNA as their genetic material.
It was the STRmix program that developed some of the DNA evidence against Paul Caniero, 57, of Ocean Township, who is charged with the 2018 murders of his brother, Keith, 50, sister-in-law ...
