摘要
"生命个体来自核酸".核酸包括核糖核酸(简称RNA)和脱氧核糖核酸(简称DNA)两类.它们都属高分子化合物,它们分子单元片段的区别在于:1在RNA中不含胸腺嘧啶而含尿嘧啶;DNA中含胸腺嘧啶而不含尿嘧啶.2在RNA分子中,核糖部分的第2’位置都带有羟基(即有氧)而在DNA分子的核糖部分的第2’位置都不带有羟基,即不含氧原子之区别.同时还介绍核糖、核苷、基因、核苷酸等概念及其它们的国际化的蒙文名称.
Lives of individuals are from nucleic acids,which includes RNA and DNA. They belong to high molecular compound,thedifferences between their molecular cell fragments are:First,RNA does not contain thymine but uracil, which is opposite in DNA.Second,in RNA molecules,there is hydroxyl(aerobic )in the second position of rebose,but there is not hydroxyl(aerobic)in the second position of ribose in DNA molecules,which is the fdifference of oxygen at-om.This paper also introduces the concept of oxygen atom.This paper also introduces the concept of ribose,nucleotide, gene,ribonucleotide and their international Mongolian names.
