A cDNA library is a collection of complementary DNA (cDNA) sequences that are synthesized from messenger RNA (mRNA) transcripts. The process of creating a cDNA library involves several key steps: 1. **Isolation of mRNA**: The first step is to extract mRNA from the cells or tissues of interest. This mRNA represents the genes that are expressed in those specific cells or conditions.
