DNA produced by combining DNA from two different organisms is known as
a mutant.
a hybrid.
a polyploidy.
Recombinant DNA.
Organisms that contain genes from other organisms are called

Which of the following is an example of uses for bacterial transformation technique?
to produce pure human insulin for use by people with diabetes
to identify a suspect based on evidence from a crime scene
to determine the nucleotide sequence of desired gene

The Human Genome Project is an attempt to
make a DNA fingerprint of every person's DNA.
identify, sequence and catalog all human DNA.
create human-like creatures.
identify alleles in human DNA that are recessive.
The purpose gene therapy in treating disorders , such as cystic fibrosis and SCIDS, is to
replace faulty genes with normal ones
determine the sequence of genes
remove mutations from genes
change dominant alleles to recessive alleles

they may cause death if eaten
they can cause allergies, toxins, new diseases and nutritional problems
they are perfectly healthy
What is the function of a restriction enzyme?
to keep DNA from replicating
to cut DNA into smaller fragments
