Front

What is genetic engineering?

Back

Genetic engineering is the process of introducing foreign DNA into a host organism to modify its genetic makeup.

Front

What is gel electrophoresis used for?

Back

Gel electrophoresis is a technique used to separate DNA fragments based on their size, allowing scientists to analyze genetic relationships.

Front

What can gel electrophoresis reveal about species?

Back

It can reveal how closely related different species are based on the similarities and differences in their DNA.

Front

What are the main steps in the polymerase chain reaction (PCR)?

Back

The main steps in PCR are denaturation, annealing, and elongation.

Front

What is the purpose of PCR?

Back

PCR is a technique that produces millions or billions of copies of a specific DNA sequence in a short amount of time.

Front

What is transformation in genetic engineering?

Back

Transformation is the process of introducing foreign DNA into a host cell, but it is NOT a step in PCR.

Front

What does denaturation refer to in PCR?

Back

Denaturation is the first step in PCR where the double-stranded DNA is heated to separate it into two single strands.

Front

What is annealing in the context of PCR?

Back

Annealing is the step in PCR where primers bind to the single-stranded DNA templates.

Front

What is elongation in PCR?

Back

Elongation is the step in PCR where DNA polymerase synthesizes new DNA strands by extending from the primers.

Front

What is gene sequencing?

Back

Gene sequencing is the process of determining the exact sequence of nucleotides in a DNA molecule.
