Question
Match the following terms with the correct definition
Column A
1. operator
2. operon
3. promoter
4. gel electrophoresis
5. polymerase chain reaction
Column B
a. the site on the DNA where a repressor protein binds and blocks the RNA polymerase from making mRNA.
b. a method widely used in molecular biology to rapidly make millions to billions of copies of a specific DNA sample
allowing scientists to take a very small sample of DNA and amplify it to a large enough amount to study in detail
c. the site on the DNA where RNA polymerase binds in order to
start transcription.
d. a unit made up of linked genes which is thought to regulate
other genes responsible for protein synthesis.
e. a technique used to separate DNA fragments according to
their size. DNA samples are loaded into wells (indentations) at one end of a gel, and an electric current is applied to pull
them through the gel.
