The technique of ________ is a means of determining the function of a gene by the phenotype resulting from its absence.
A) gene therapy
B) gene knockout
C) probe analysis
D) expression vector cloning
E) FISH

Question

Quizplus · Accepted Answer

Gene knockout is the technique used to determine the function of a gene by creating an organism that lacks the gene's expression or product. By studying the resulting phenotype of the organism without the gene, researchers can infer the gene's function. Gene therapy (A) is a technique used to correct genetic disorders by introducing functional genes into a patient's cells. Probe analysis (C) is a method to detect specific DNA sequences or genes in a sample. Expression vector cloning (D) is a technique used to produce and isolate large amounts of a specific protein from a gene of interest. FISH (E) is a technique used to visualize the location of specific genes or DNA sequences in cells or tissues.
