Name the lab technique that produced this

What are we looking at?

• DNA segments that are separated by size

• Chromosomes

• Recessive genes

• To locate genes of interest based on size.

What is this called?

• electrophoresis

• karyotype

• dna fingerprinting

• cloning

What is this technique used for?
