He was awarded the Nobel Prize in Physiology and Medicine in 1962. DNA is an abbreviation of "deoxyribonucleic acid", which is composed of two long spiral strands. It is a biological macromolecule that can compose genetic instructions and make biological development and life functions operate. The main function is information storage, which can be likened to "blueprint" or "recipe" 【specification】 Material: Alloy Color: Gold / Silver Chain length: 40 + 5cm Comes with simple packing carton https://live.staticflickr.com/65535/49177121707_dcf1cc4eab_o.jpg https://live.staticflickr.com/65535/49176419478_1aeb1f164b_o.jpg 【Precautions】 ▶ Do not come into contact with water or wear a bath for a long time. ▶ Do not directly touch products containing chemical additives, such as perfumes, styling sprays, chlorine in swimming pools, etc. ▶ If you do not wear it for a long time, wipe it with a clean cotton cloth.
