AB Chapter 12 Genetic Engineering

Combining DNA from two sources is known as

• gene cloning

• transformation

• recombinant DNA

• vector

An organism that is used to transfer a gene from one organism to another is known as a

• vector

• clone

• bacteria

• plasmid

What type of protein cuts DNA at specific locations?

• restriction enzymes

• DNA ligase

• DNA polymerase

• helicase

The part of a bacteria cell that is used as a vector is a _________.

When plasmids are used to produce proteins the plasmid re-enters the bacteria by what process of DNA exchange?

The function of DNA polymerase is to

• bind the DNA backbone together

• cut DNA at a specific location

• unzip the DNA double helix

• add nucleotides to build a DNA strand

The major source of restriction enzymes are

• plant cells

• bacteria cells

• human cells

• DNA

What is a "sticky end"

• DNA fragments with single stranded ends

• fragments of RNA

• DNA fragments with double stranded ends

• fragments of RNA with double stranded ends

The production of many identical copies of a gene-carrying piece of DNA is called gene ___________

What enzyme can be used to convert mRNA into DNA?

• reverse transcriptase

• reverse DNA polymerase

• reverse ligase

• reverse helicase
