The process of removing DNA from cells is called

• DNA fingerprinting

• DNA extraction

• Recombinant DNA

• Transgenics

Which process is used to make many copies of a DNA sample?

• gel electrophoresis

• DNA sequencing

• Restriction enzyme producing DNA fragments

• PCR

What is the function of gel electrophoresis?

• to separate DNA fragments according to size and charge

• to cut DNA

• to recombine DNA

• to extract DNA

During transformation,

• a prokaryote is changed into a eukaryote.

• a cell takes in DNA from outside the cell.

• plasmids are inserted into a human cell.

• a cell is mutated.

A small circular molecule of DNA found in bacteria cells is called a

• chromosome

• recombinant DNA

• genetic marker

• plasmid

DNA produced by combining DNA from two different organisms is known as

• a mutant.

• a hybrid.

• a polyploidy.

• Recombinant DNA.
