LactoseSynthesis
The synthesis of glycosidic bonds between monosaccharides requires energy input, energy that is provided by joining sugar monomers to a nucleotide such as UDP. Glycosyl transferases join two sugar monomers together, with UDP as the leaving group that drives the reaction forward. One glycosyl transferase is galactosyl transferase. Galactosyl transferase catalyzes the formation of a glycosidic bond between galactose an......阅读全文

DNA合成（DNA－synthesis－）技术介绍
蛋白质概念提出：DNA多肽合成（DNA synthesis ）：按照预定核苷酸的顺序，将脱氧核苷酸逐个进行人工连接合成DNA链的方法。目前多是采用固相合成法，即是在多聚体支持物上从3′端延伸核苷酸，可自动化操作。)目前，oligo DNA合成一般都采用固相亚磷酰胺三酯法合成DNA片段，此方法具有高效
