紫茉莉的非孟德尔遗传现象 1909年,法国植物学家C. Correns报道了紫茉 莉中不符合孟德尔定律的遗传现象

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

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

第一节遗传工程概述 遗传工程广义:细胞工程、染色体工程 细胞器工程、基因工程

Using mutants to analyze the pathway or functions of genes Mutants have to be generated to analyze the pathway or functions of genes Saturation screening Overexpression Suppressor mutations Synthetic lethals Nonallelic noncomplementation
