The Study of Cells

Question 18 • Anatomy & Physiology A

What is genetic tagging?

Answer

a technique that uses specific antibodies to visualize features of cells

a technique that visualizes how specific genes are used within a cell

a technique in which cells are purposefully grown under specific conditions

an imaging technology used to study features smaller than the human eye can see

Explanation

Genetic tagging links a gene of interest to a detectable marker, so researchers can see where or when that gene is active in a cell. This matches choice B, visualizing how specific genes are used within a cell. Antibodies can label cell features, but that is a different technique.
