History of DNA - What is DNA & How Was It Discovered ...

Posted: (3 days ago) DNA works by copying itself into that single-stranded molecule called RNA. If DNA is the blueprint, you can think of RNA as the translator of instructions written in the blueprint. During this process, DNA unwinds itself so it can be replicated. RNA is similar to DNA, but it does contain some significant molecular differences that set it apart.

DNA - Wikipedia

Posted: (3 days ago) 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.

DNA History - The Discovery of DNA

Posted: (3 days ago) While DNA (DeoxyriboNucleic Acid) was discovered in 1868, it wasn't recognized as genetic material until almost a century later. DNA was discovered by a Swiss medical student named Johann Friedrich Miescher, who found it when working with white blood cells that he took from pus drained out of a surgical wound.He determined that the nuclein was rich in phosphorous and was also acidic.
