Figure 8.1 Base Substitution Shown here is the generation of a mutant organism as a result of the incorporation of a pyrimidine base (cytosine) in place of thymine in DNA replication.The mutation is a missense mutation.

neously from one site to another in the same or different DNA molecules, a process called transposition. Any gene into which a transposable element inserts itself is disrupted, so that it no longer codes for a functional protein. The gene usually suffers a knockout mutation in transposition. The structure and biology of transposons will be considered later in this chapter.
