mRNAcDNA

mRNAcDNA refers to complementary DNA synthesized from messenger RNA (mRNA). This process, known as reverse transcription, utilizes an enzyme called reverse transcriptase. Naturally, mRNA serves as a template for protein synthesis within a cell, carrying genetic information transcribed from DNA. However, DNA is a more stable molecule than mRNA. By converting mRNA into cDNA, researchers can create a more stable and easier-to-manipulate DNA version of the genetic information that was being expressed as mRNA. This cDNA can then be used in various molecular biology techniques, such as cloning, PCR amplification, and gene expression analysis. Reverse transcription-polymerase chain reaction (RT-PCR) is a common method that combines reverse transcription to produce cDNA with PCR to amplify specific cDNA sequences. This allows for the detection and quantification of specific mRNA molecules in a sample, providing insights into gene activity. The cDNA produced is double-stranded, meaning it has a complementary strand synthesized against the initial single-stranded cDNA.
