RT-PCR · Pathology

In a Real-Time RT-PCR (RT-qPCR) assay, the term 'Relative Quantification' refers to:

  1. Determining the exact number of viral copies per milliliter
  2. Normalizing target gene expression to a housekeeping gene
  3. Measuring the total weight of RNA in the sample
  4. Estimating the ratio of DNA to RNA
Show answer and explanation

Correct answer: Normalizing target gene expression to a housekeeping gene

Relative quantification normalizes the expression of a target gene against a reference gene (like GAPDH or ACTB) that is expressed at a constant level. This accounts for variations in sample loading and RNA quality between different specimens.
