How Does a DNA Test Work?
DNA testing is becoming increasingly advanced with every passing year. From the simplest bacteria to the emotional sack of cells called humans, every living organism carries an instruction manual in every cell. This, of course, is DNA, which is a long string of the letters A, T, G, and C which encodes the information fundamental to human life. In humans, the string of DNA is about 6 billion letters long. How these 6 billion letters guide us from the moment that sperm meets egg through the rest of our life has driven hundreds of years of research. A, T, G, and C are the four nucleotides. A pairs with T & G pairs with C. Genetic information is stored in the precise sequence of these nucleotides. Change one letter, and your cell may start acting very differently.
