DNA Technology

An electrical current is used to separate a mixture of DNA fragments from one another.

• Cloning

• gene sequencing

• restriction map

• gel electrophoresis

These show the length of DNA fragments between restriction sites in a strand of DNA.

• restriction maps

• cloning

• gene sequencing

• bioinformatics

A representation of parts of an individual's DNA that can be used to identify a person at the molecular level.

• transgenic

• gene sequencing

• genomics

• DNA fingerprinting

A genetically identical copy of a gen or of an organism.

• genomics

• plasmid

• clone

• gene sequencing

The changing of an organism's DNA to give the organism new traits.

• recombinant DNA

• genomics

• bioinformatics

• genetic engineering

DNA that contains genes from more than one organism.

• recombinant DNA

• restriction enzyme

• plasmid

• DNA microarray

Mapping and sequencing all of the DNA base pairs of the human chromosome and identify all the genes within the sequence.

• PCR

• human genome project

• Restriction mapping

• bioinformatics

The process of testing DNA to determine a person's risk of having or passing on a genetic disorder.

• gene sequencing

• gene therapy

• genome

• genetic screening

The parents of a new baby believe they brought the wrong child home from the hospital. Gel electrophoresis was performed using DNA samples from the parents and the child. A section of the gel electrophoresis results is shown below. Which conclusion is valid based on the gel electrophoresis results?

• They have the correct child, because her genetic information is identical to that of the father.

  
  

• They have the wrong child, because her genetic information does not match that of either parent.

• They have the correct child, because her genetic information came from both parents.

  
  

• They have the wrong child, because her genetic information matches only that of the mother.

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
