1. Base(s) in DNA is (are) changed to other(s), or a base(s) is (are) added or removed. 2. Rearrangements of the chromosomes occur and are also considered

These entities encode information essential for the construction and regulation of proteins (such as enzymes) and other molecules that determine the growth and functioning of the organism

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

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)
