Question 21

 

What are some current DNA recombinant technologies, and some practical applications of nucleic acid technology? [Chapter 20]

 

DNA Cloning (read pages 376-382)

 

  1. DNA technology makes it possible to clone genes for basic research and commercial applications.

 

  1. Restriction enzymes are used to make recombinant DNA.

 

  1. Genes can be cloned in recombinant DNA vectors.

 

  1. Cloned genes are stored in DNA libraries.

 

  1. The polymerase chain reaction (PCR) clones DNA entirely in vitro.

 

DNA Analysis and Genomics (read pages 383-393)

 

  1. Restriction fragment analysis detects DNA differences that affect restriction sites.

 

  1. Entire genomes can be mapped at the DNA level.

 

  1. Genome sequences provide clues to important biological questions.

 

Practical Applications of DNA Technology (read pages 393 to 399)

 

  1. DNA technology is reshaping medicine and the pharmaceutical industry.

 

  1. DNA technology offers forensic, environmental, and agricultural applications.

 

  1. DNA technology raises important safety and ethical questions.
