6.8: Biotechnology Flashcards
1
Q
Both DNA and RNA can be manipulated through ____ _______
A
Genetic engineering
2
Q
What is gel electrophoresis?
A
A technique used to separate DNA fragments by size
3
Q
How does gel electrophoresis work? (3)
A
- DNA is loaded into walls on one end of a gel
- Electric current is applied
- DNA fragments are negatively charged, so they move towards the positive electrode
4
Q
What is a polymerase chain reaction (PCR)?
A
- a method used in molecular biology to make several copies of a specific DNA segment
- segments of DNA are amplified
5
Q
How can the results of a PCR test be analyzed?
A
Using gel electrophoresis
6
Q
What is DNA sequencing?
A
The process of determining the order of nucleotides in DNA
