PCR and Gel Electrophoresis

Which DNA tech is responsible for multiple copies of a gene?

• Gel electrophoresis

• PCR

• Sequencing

• Transformation

Gel electrophoresis separates molecules based on

• Charge and Polarity

• Polarity and Weight

• Weight and Size

• Size and Charge

In a gel electrophoresis…

• More numerous sizes are near the wells

• Less numerous sizes are near the wells

• Larger molecules are near the wells

• Shorter molecules are near the wells
