摘要：DNA作为遗传物质应该具备两个基本功能,一是遗传信息在时代见的传递,从而保证物种的延续和遗传的稳定性,二是在细胞和个体的生长发育等过程中得以表达,从而表现出与亲代相似的性状.必须准确进行DNA复制.1953年Watson和Crick提出DNA双螺旋结构模型和DNA半保留模型.在1958年首先由Meselson和Stahl以大肠杆菌为材料,利用N15及N14同位标记的实验证实了DNA半保留复制模型的正确性.此后Cairns在1963年对大肠杆菌DNA放射自显影实验以及Taylor在1958年进行的蚕豆染色体放射自显影实验,都说明真核与原核生物一样,DNA的复制方式都是按半保留方式进行的.

Answer 1

DNA as the genetic material should have two basic functions,first,to see the era of genetic information transfer,thus ensuring the continuation of species and genetic stability,and second,in the cell and individual growth and development of such processes can be expressed,thus demonstrating similar to the parental traits.Must be accurate,DNA replication.In 1953 Watson and Crick proposed model and the DNA double helix structure of DNA semi-conservative model.In 1958,the first by Meselson and Stahl E.coli as the material,the use of N15 and N14 with the bits labeled DNA test confirmed the correctness of semi-conservative replication model.
After Cairns in 1963 of E.coli DNA autoradiography experiments,and Taylor in 1958,carried out in broad bean chromosome autoradiography experiments,were indicative of eukaryotic and prokaryotic like,DNA replication methods are carried out by semi-conservative manner.
