How do scientists cut DNA into smaller strands?

• restriction enzymes
• scissors
• ligase
• agarose

The process of making changes in the DNA code of a living organism is called

• selective breeding 
• genetic engineering
• inbreeding
• hybridization

Two organisms that are closely related would have

• very similar DNA sequence
• exactly the same DNA sequences
• no proteins in common
• completely different DNA sequence

What is recombinant DNA

• DNA from 2 different organisms combined

• DNA from 2 different ribosomes

• DNA that is separated out from a vector

In which ways can genetic engineering can improve crops

• Make them pest or drought resistant

• Make them more nutritious

• Make them larger

• All answers are correct

A circular piece of DNA, found in bacteria, is called:

• A plasmid

• mRNA

• Ribosome

• Nucleotide

When DNA is manipulated and moved from one source to another it is known as

• genetic engineering
• electrophoresis
• gene therapy
• GMO

Gel electrophoresis enables scientists to

• separate DNA fragments.
• combine DNA fragments.
• count the genes in DNA.
• insert DNA in cells.
