Identify one transgenic organism from this chapter. Describe how it
was created. Then use your imagination to think of another possible
transgenic organism that could be made and identify the original
organisms that could be used to make it.

Complete the paragraph about DNA tools by using the words below.


  • blunt ends • Eco RI • gel electrophoresis

  • restriction enzymes • sticky ends


Scientists use to cut DNA at specific
sequences, and to separate fragments
based on size. Some create DNA with
single-stranded,.
is an example of this type of enzyme. The resulting DNA fragments
can be joined with other DNA fragments that have complementary

. Other create
, which can be joined to another DNA
fragment that has.


Compare the DNA tools and techniques used in genetic engineering.

Genetic Engineering Application Tool or Technique Used
Make millions of copies of a region
of DNA
Determine the order of nucleotides

Chemically join together two
fragments of DNA
Carry recombinant DNA into
bacteria
Produce large amounts of
recombinant DNA
