A: 1986
2. What is the purpose of an enzyme in DNA process?
A: To "cut and paste" DNA.
3. Has a human ever been clone?
A: No. Many plants and animals have been cloned in the past, but ethical issues keep the science from being tested on humans.
Five Main Facts From The Reading:
1.Genes can be cloned in recombinant plasmids.
2.Cloned genes can be stored in genomic libraries.
3.Reverse transcriptase can help make genes for cloning.
4.Nucleic acid probes identify clones carrying specific genes.
5.Recombinant cells and organisms can mass-produce gene products.

Ten Key Terms:
1. Biotechnology - the manipulation of organisms or their components to make useful products.
2. DNA technology - methods for studying and manipulating genetic material.
3. Plasmids - small, circular DNA molecules that replicate separately from the much larger bacterial chromosome.
4. Gene cloning - the production of multiple identical copies of a gene-carrying piece of DNA.
5. Genetic engineering - the branch of biotechnology that involves the direct manipulation of genes for practical purposes.
6. Restriction site - the DNA sequence recognized by a particular restriction enzyme.
7. Genomic library - the entire collection og all the cloned DNA fragments from a genome.
8. Vaccine - a harmless variant or derivative of a pathogen that is used to stimulate the immune system to mount a defense against the pathogen.
9. Gene therapy - alteration of an afflicted individual's genes.
10. DNA profiling - the analysis of DNA fragments to determine whether they come from a particular individual.

Summary:
This chapter was all about how genetic information is put to practical use in every day life, and in many different careers. It showed that the ability to understand DNA and it's role in organisms has improved life for many people, and that on some occasions it has even saved lives.
