Genetic Engineering (Chpt 15 review)

DNA from one organism is COMBINED with DNA from another organism. The resulting molecules are called

• a mutant

• a hybrid

• recombinant DNA

• a polyploid

Answer explanation

DNA from one source is COMBINed with DNA from another source = reCOMBINant DNA

Combining a lion and a tiger to create a liger is an example of

• inbreeding

• transformation

• a polyploid

• hybridization

TransGENIC organisms are created using

• genetic engineering

• hybridization

• inbreeding

• gel electrophoresis

Answer explanation

What enables scientists to make multiple copies of DNA?

• mutations

• gel electrophoresis

• polymerase chain reaction

• transformation

Answer explanation

Higher yield crops

• require more land

• produce less using the same acreage

• produce more using the same acreage

• occur naturally

Answer explanation

higher yield = MORE growth in SAME area (picture on the right)

Breeding genetically similar organisms that can result in a genetic defect is

• hybridization

• transformation

• polymerase chain reaction

• inbreeding

Answer explanation

No two people have the same DNA except

• mother and child

• father and child

• fraternal twins

• identical twins

Answer explanation

IDENTICAL twins have the SAME DNA

A cloned organism has the SAME DNA as

• the donor of the nucleus

• the donor of the egg cell

• the foster mother

• the DNA is different from all of them

Answer explanation

The NUCLEUS donor and the CLONE have IDENTICAL DNA b/c DNA is found in the nucleus

Restrictions enzymes

• create DNA fragments with sticky ends

• separates DNA fragments by size

• are needed for hybridization

• are used to develop a pedigree

Answer explanation

Which of the following might an animal breeder use to create EXACT copies of an animal with desired traits?

• hybridization

• inbreeding

• polymerase chain reaction

• cloning

Answer explanation

clones are EXACT copies
