BioTech Review

Biotechnology is the manipulation of living organisms or their components to produce useful, usually commercial products.

• True

• False

The point of genetic engineering is to transfer useful traits/characteristics such as:

• pest resistance

• disease resistance

• drought tolerance

• anti-bruising

• All of the above

Using biotechnology to change the genetic makeup of an organism is called

• Tissue Culturing
• Biotechnology
• Cloning
• Genetic Engineering

GMO stands for

• Genetically Made Organism
• Growing More Organisms
• Genetically Modified Organism
• Growing Many Organisms

How has genetic engineering helped farming?

• by developing better fertilizer for crops

• by creating crops that resist some diseases

• by producing soil that makes crops grow better

• by producing faster ways to harvest crops

NGSS.HS-LS2-7

This laboratory procedure is known as

• CLONING

• gel electrophoresis

• chromatography

• use of a dichotomous key

In preparation for an electrophoresis procedure, enzymes are added to DNA in order to

• convert the DNA into gel

• cut the DNA into fragments

• change the color of the DNA

• produce longer sections of DNA

A student performed a gel electrophoresis experiment. The results are represented in the diagram

below. Compared to the fragments at the top of the gel, the fragments at the lower end are

• larger, and move slower

• larger, and move faster

• smaller, and move faster

• smaller, and move slower

Which chemicals are used to cut DNA into fragments for a gel electrophoresis procedure?

• enzymes

• molecular bases

• hormones

• ATP molecules

This technique used to analyze DNA involves the

• synthesis of new DNA strands from subunits

• separation of DNA fragments based on size

• production of genetically engineered DNA molecules

• removal of defective genes from DNA
