Once the gene and plasmid have been cut with a restriction enzyme, another enzyme called _________ is used to join the pieces of DNA together.

• polymerase
• ligase
• dehydrogenase
• lactase

The unpaired nucleotides produced by the action of restriction enzymes are referred to as

• sticky end.
• base sequence.
• single strands.
• restriction fragments.

A ____________ is required to transfer genes from one organism to another.

• vector

• genetic probe

What does PCR stand for?

• Polymerase Chronic Reagent
• Principle Chorionic Reliability
• Polymerase Chain Reaction
• Probably Cannot React

This laboratory procedure is known as

• gel electrophoresis

• chromatography

• use of a dichotomous key

What is the purpose of gel electrophoresis?

• helps cut DNA
• count the genes in DNA
• separates DNA based on size
