100
Fragments are sorted by this in gel electrophoresis.
What is size?
100
PCR stands for this.
What is polymerase chain reaction?
100
This type of DNA contains genes from more than one organism.
What is recombinant DNA?
200
The DNA fragments move toward the positive electrode since DNA has this type of charge.
What is a negative charge?
200

The purpose of PCR

making rapid copies of a DNA fragment

200
This is commonly used in genetic engineering.
What is bacteria?
300
This diagram shows the lengths of fragments between restriction sites in a strand of DNA.
What is a restriction map?
300
The DNA polymerase used in the process of PCR.
What is Taq polymerase?
300
These closed loops of DNA separate from the bacterial chromosome and replicate on their own within a cell.
What are plasmids?
400
This separates a mixture of DNA fragments from each other.
What is an electrical current?
400
The three steps that occur in the PCR method.
What are separating, binding, and copying?
400
Genetic engineering gives these to organisms.
What are new traits?
500
The way in which the length of a DNA fragment can be estimated.
What is measuring the distance it travels through a gel in a certain period of time?
500
The four materials used in PCR.
What are DNA polymerases, the DNA to be copied, large amounts of the four DNA nucleotides, and two primers?
500
The reason genetic engineering is possible.
What is the genetic code shared by all organisms?
