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
