Biotechnology

The entire collection of genes within human cells is referred to as the ______.

• human genome
• karyotype
• pedigree
• gene map

A genome is

• part of a chromosome
• a gene inserted into a chromosome of bacteria
• a sequence of units in a short segment of DNA
• the complete sequence of an organism’s DNA  
  

A lab technique used in crime fighting to prove a suspects innocence or guilt is known as:

• genetic engineering
• PCR
• electrophoresis
• gene therapy

Which of the following would be an example of gene therapy technology?

• development of a nasal spray that contains copies of the normal gene that is defective in person with cystic fibrosis
• cutting DNA into fragments with restriction enzymes
• modifying E. coli to produce indigo dye for coloring denim blue jeans
• separation DNA fragments using gel electrophoresis

This is the practice of producing a genetically identical cell or organism

• Cloning

• Gel Electrophoresis

• Genetic Engineering

• DNA Fingerprinting

What is recombinant DNA?

• Adding DNA from one organism into the DNA of another
• DNA which has been changed over generations by natural selection
• DNA that causes genetic disorders
• DNA that has been sequenced

True or False: Gel electrophoresis allow scientist to compare DNA of different individuals.

• True
• False

The graphic shown here is called a

• PCR

• DNA fingerprint

• electrophoresis gel

Which suspect left the blood stain?

• Bob

• Sue

• John

• Lisa

DNA fingerprinting works because

• Most genes are dominant
• All organisms contain RNA
• The most important genes are different among most people
• No two people, except identical twins, have exactly the same DNA
