Gene Splicing

Transgenic organisms are .......

• It is another name for a clone.

• Organisms that a gene is taken out of to be put into another species.

• organisms that receive a gene from a different species.

• The enzymes that cut DNA.

What is recombinant DNA?

• DNA from 2 different organisms combined

• DNA from 2 different parents combined

• It is the same as DNA replication.

A circular piece of DNA, found in bacteria, is called:

• A plasmid

• double helix

• nucleus

Making changes in the DNA of an organism is

• Done often with food crops

• a bioethical issue

• genetic engineering
• all these answers are correct.

When human DNA is inserted in bacterial DNA to create insulin, the DNA is called

• human

• bacterial DNA
• recombinant DNA
• target gene

Biotech foods look and taste the same as traditional foods and crops. The only difference is that biotech food has

• fewer calories.
• the addition of specific minerals.
• genes with traits that improve something about the plant.
• a better chance of surviving a frost during the growing season.

When making a DNA Fingerprint, which molecule is used to cut DNA into DNA fragments?

• DNA helicase
• DNA polymerase
• restriction enzyme
• transgenic enzyme

When making a DNA Fingerprint, the gel electrophoresis machine filters the DNA by size. Which fragments make it further down in the gel?

• shorter
• longer
• codons
• anticodons

During transformation, a cell

• is treated with radiation.
• has two genetically different parents.
• has foreign DNA inserted in its chromosome.
• has parents of different species.

T6- Which technology below would probably be the most important to a person who had diabetes and had to take insulin every day? 

• using recombinant DNA to produce human hormones from bacteria
•  testing parents for genetic disorders before they have children
• engineering fruits and vegetables that resist insects and other pests
• C. developing ways to identify criminals through DNA fingerprinting
