Overview and Objectives - DNA and DNA Extraction
This lesson discusses what DNA is and how it relates to genes and chromosomes. How and why DNA is extracted in the genetic engineering process is also covered. At the completion of this lesson, you should be able to:
- Visualize the relationship between DNA, genes, and chromosomes.
- Compare the roles that DNA and proteins play in a cell.
- Explain how proteins are made from DNA (the processes of transcription and translation).
- Contrast DNA and proteins in their chemical make-up.
- Explain why DNA extraction is important in genetic engineering and how it is done.
- Understand why genes can be transferred between organisms and still work.
