Electrophoresis & DNA Profiling

ELECTROPHORESIS IS DONE FOR

• DNA EXTRACTION

• DNA FRAGMENTATION

• SEPARATION OF DNA FRAGMENTS

• DETECTION OF HYBRIDISED DNA

Which enzyme is used for digestion of DNA?

• Restriction endonucleases

• Lyases

• Ligases

• DNA polymerase

DNA fingerprinting is used in

• Forensic science

• Paternal disputes

• Research work

• All of the aove

To separate DNA fragments which technique is used?

• Gel Electrophoresis

• Blotting

• Sequence annotation

• Northern blotting

Whose blood was found at the crime scene?

• John
• Lisa
• Bob
• Sure

Gel electrophoresis is used to separate DNA fragments on the basis of which property?

• size

• color

• functions

• chromosomes

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 special protein that targets a specific base sequence and cuts DNA into smaller fragments is a(n)

• Gene

• DNA Probe

• Exon

• Restriction Enzyme

Which DNA fragment bands move faster and farther in a gel electrophoresis? 

• there is no way to tell 
• the largest ones
• the smallest ones
• none of these

Restriction enzymes cut DNA at locations called

• vectors

• palindromes

• genomes

• active sites
