Genetic Engineering CH. 13

Selective Breeding Allowing only those with desired character istics to produce the next generation

Inbreeding Continued breeding of individuals with similar characteristics Useful in retaining a certain set of characteristics Can produce some serious genetic defects

Genetic Engineering DNA extraction Cutting DNA Separating Remove DNA from cell Cutting DNA Restriction enzymes cut DNA into smaller fragments Separating Gel electrophoresis

Using the DNA Sequence Read the Sequence Cutting and Pasting Based on the base pairs Cutting and Pasting Recombinant DNA Made by combining DNA from different sources Making Copies

Applications of Genetic Engineering Transgenic Organisms Contain genes from other organisms Usually bacteria because they reproduce rapidly and are easy to grow.

Cloning A clone is a member of a population of genetically identical cells produced from a single cell.
