DNA是一个多聚脱氧核苷酸链和最大的生物大分子；一些DNA分子包含超过108个核苷酸。基本含有腺嘌呤、胸腺嘧啶、鸟嘌呤、胞嘧啶，遗传信息编码的核苷酸序列被精确定义在整个分子上。有一种最简单的方法可以确定DNA的核苷酸序列，那就是利用DNA聚合酶,它是用来催化合成的DNA的
DNA是一种多聚脱氧核苷酸，其中最大的生物大分子；一些DNA分子包括超过108个核苷酸。它们含有腺嘌呤，胸腺嘧啶，鸟嘌呤，胞嘧啶为基地，和遗传信息的编码核苷酸序列内，这正是定义在分子的整个长度。用于测定DNA的核苷酸序列的最简单的方法之一是利用一种酶，它催化的DNA聚合酶，DNA的合成
DNA是一个多聚脱氧核苷酸、也是最大的生物大分子之一；一些DNA分子包含了超过108个核苷酸.其中以腺嘌呤、胸腺嘧啶、鸟嘌呤、胞嘧啶为基础,而遗传信息则由核苷酸序列的编码方式确定,这样就能保证其在整个DNA分子...
