WebOct 1, 2024 · The reporter gene is transcribed and translated by the transfected cells, and depending on the actual reporter gene used, its activity may be detected directly or indirectly through the ability of its encoded protein to convert a substrate to a detectable product. The latter scenario is illustrated in Figure 1. Figure 1. WebApr 7, 2024 · Transcription refers to the first step of gene expression where an RNA polymer is created from a DNA template. This reaction is catalyzed by enzymes called RNA polymerases and the RNA polymer is antiparallel and complementary to the DNA template.
