Objectives for Gene Cloning Part 1

This lesson describes how DNA molecules can be recombined to make recombinant DNA and how special DNA molecules called plasmids allow scientists to clone genes.

Objectives: At the completion of this lesson you should be able to:

  1. Define gene cloning, gene library, plasmid, recombinant plasmid and vector.  
  2. Outline and describe the steps of the process used to make genomic and cDNA libraries.  
  3. Explain the role of antibiotic resistance and selectable marker genes in the gene cloning process.  
  4. Contrast libraries that use plasmids as vectors to BAC or YAC libraries.
