DNA was first discovered thanks to fellows named Francis Harry Compton Crick who was a English molecular biologist and biophysicist, neuroscientist. And James Dewey Watson who was American molecular biologist, geneticist, and zoologist. Both Crick and Waston were the co discovers of struction of DNA in year 1953. Grouping a team together as both bringing enlightening commons. Cricks had been highly interested in two fundemental unsolved biologcal problems, as being how molecules create transition from nonliving to living and second, how the brain makes conscious mind. While Watson was highly drawn into molecular biology by the work of Salvador Luria.
DNA provides help for many situations such as genetic finger prints, alongside test helping pinpoint treatments for cancer patients, evidence, much help directly for scientist experiments which being majoraly important in our past times for which discoveries of new medicines and similar encouterments like mutation in chromosomes. Also, solve crime statistic including investigation, catching criminals and identifying specific disease.
Without DNA, our modern times would be hopelessly losted with little insurance of help and security.
