• Regions of noncoding DNA

• DNA fragments with genes

• The X and Y chromosomes

DNA fingerprinting can be used to

• Assess actual disease risk

• Prove a family relationship

• Find all recessive alleles

• Measure gene expression

Which of the following are examples of clones?

• They contain bacterial genes

Plants that contain recombinant DNA are called

• Clones

• Knockouts

• Transgenic

• Plasmids

Bacterial enzymes that cut the DNA of viruses are called
