[0002] mRNA (messenger RNA) is a type of molecule that carries genetic information in cells. Its function in organisms is mainly to transfer genetic information in DNA to the cytoplasm and guide protein synthesis. The synthesis of mRNA begins with genes on DNA, and the genetic information is transcribed into mRNA through the transcription process. After transcription, mRNA may undergo a splicing process, in which the combination of non-coding regions (non-coding sub-regions) and coding regions (coding sub-regions) may change. The activity of mRNA is directly related to the regulation of gene expression. Cells achieve precise control of gene expression by regulating the synthesis, stability and translation of mRNA. Therefore, studying the activity of mRNA helps to gain a deeper understanding of the gene regulatory network, so a detection device for quantitative addition of mRNA stock solution in in vitro activity measurement is proposed.
