Restriction enzymes are used for cutting DNA at precise locations Vectors are used for the propagation of cloned DNA fragments Libraries of cloned DNA fragments allow searching for a specific DNA fragment

基因类别 结构基因包括编码结构蛋白和酶蛋白的基因, 也包括编码阻遏蛋白和激活蛋白的基因。 调控基因包括调节基因、启动基因和操纵基因

How DNA as genetic materials was established (also summarized in er including structure and components Basic properties of DNA, i xt slide)

There are many ways of cloning a disease gene, depending on what is known about the disease. We will show several typical examples in this part of the lecture
