Question

Which technology is shown in the diagram?

A. Gel electrophoresis
B. Biostimulation reaction
C. Polymerase chain reaction
D. Restriction enzymes

Answer 1

That is a PCR (Polymerase Chain Reaction) used to make copies of DNA or RNA strands

Answer 2

The correct answer is C. Polymerase chain reaction

Step-by-step explanation:

The diagram shows the molecular biology technique Polymerase Chain Reaction (PCR), which is used to amplificate quantities of DNA. The technique uses the intrinsic ability of DNA polymerase, a enzyme which adds nucleotides to a short fragment of DNA- a primer- by using a single strand DNA as template. Furthermore, the often used DNA polymerase is from a thermofilic microorganisms, so the enzyme can catalyze the polimerization reaction at high temperatures- which is very useful to controlling the reaction. Through this technique, in each cycle of reaction the initial quantity of DNA is exponentially amplified.
