Document Summary

A practical use of our understanding of heredity . Genetic engineering - changing the phenotype by changing its dna to make it more useful/desirable. Gene cloning - taking a single gene form one organism and putting it in another organism. Selective breeding technology (i. e. domestication of plants and animals) Only technology required is the ability to select and breed the next generation. Can wait for useful mutations to arise by chance and/or cross two related species. limitations: i. ii. Must wait a long time for the right gene to mutate into a new form. Must be able to cross two closely related species. Cabbage + radish = cadish? (result leafy part of radish and roots of cabbaget. t) To make an organism express a new phenotype. To understand how the gene itself works (in isolation) Example: diabetes and insulin - cloning a gene to make bacteria produce a useful protein.
