生物体的物质组成可分为无机物和有机物两大类。无机物包括水和无机盐;有机物包括蛋白质、核酸、多糖和脂类。核酸分为核糖核酸和脱氧核糖核酸。 脱氧核糖核酸即DNA,由腺嘌呤(A)、鸟嘌呤(G)、胞嘧啶(C)、胸腺嘧啶(T)四种核苷酸组成。处在不同状态下,它们可产生有信息和无信息的变化。 这激起了科学家们研制生物电子元件的灵感——生物计算机(第六代计算机),有可能在下世纪被推向世界。 核糖核酸即RNA,由腺嘌呤(A)、鸟嘌呤(G)、胞嘧啶(C)、尿嘧啶(U)四种核苷酸组成。它们有不同的排列顺序,构成了不同的生命密码。 科学家们预言:下世纪将是生命科学的世纪,可破译人类的生命和遗传密码,科学地对此进行解释,并可揭示生命和遗传秘密的全过程,极大地提高人类素质。
Organisms of the material composition can be divided into two categories of inorganic and organic matter. Inorganics include water and inorganic salts; organic matter includes proteins, nucleic acids, polysaccharides and lipids. Nucleic acids are divided into ribonucleic acid and deoxyribonucleic acid. DNA, or DNA, consists of four nucleotides, adenine (A), guanine (G), cytosine (C) and thymine (T). In different situations, they can produce both informed and non-informative changes. This has inspired scientists to develop bio-electronic components inspired by - the biological computer (the sixth generation of computers), is likely to be pushed to the world in the next century. Ribonucleic acid, RNA, consists of four nucleotides, adenine (A), guanine (G), cytosine (C) and uracil (U). They have different arrangement order, constitute a different life password. Scientists predict that the next century will be the century of life science, which can decipher human life and genetic code, explain it scientifically, reveal the whole process of life and genetic secrets, and greatly improve human qualities.
