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

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

Why do the fragments of DNA in gel electrophoresis travel away from the negative electrode?

DNA is negatively charged so attracted to the positive end of the unit

DNA is positively charged to attracted to the negative end of the unit

the agarose gel in negatively charged

the agarose gel is positively charged

In gel electrophoresis, the largest DNA fragment will appear

closest to the starting wells

farthest from the starting wells

three quarters away from the starting wells

it depends on how many fragments there are

Which is the primary purpose of using restriction enzymes in gel electrophoresis?

It allows the strands of DNA to be cut into various lengths for testing

It restricts the number of base pairs that can be tested in a sample

It makes the testing simpler by moving the strands into the gel faster

It charges the DNA strands

The DNA fingerprint pattern of a child is

75% similar to the father

75% similar to the mother

50% bands similar to father and rest similar to mother

Exactly similar to that of both of the parents

Mitochondrial DNA is inherited from the father.

True

False

What is transformation?

The use of viruses to transform or genetically

engineer cells.

The measure of how well cells are transformed in a new phenotype.

The insertion of a foreign plasmid into a bacterial cell which results in new acquired traits.

Genetic engineering or transformation of mammalian cells.

10.

Cells are made competent by;

The incubation of the bacteria at 95C

A process that uses calcium chloride.

A process that uses GFP

A process that uses polymerases

11.

Heat shock

Trap the plasmids inside the cell.

Enlarges the pores of the cell.

Provides for the death of the cell.

Increases the disintegration of the cell wall.

12.

What is used to ensure the bacteria transformed with the gene for antiobiotic resistance as only the transformed bacteria will grow on this medium?

ampicillin

16.

Which gene is responsible for making the bacteria resistant to ampicillin?

ampR

pGLO

araC

GFP

17.

What is the name of the plasmid we used TO TRANSORM THE BACTERIA?

GFP

bla

araC

pGLO

18.
