Polymerases are key enzymes for the synthesis of nucleic acid polymers. It plays a crucial role in DNA metabolism, regulating different processes such as mitosis, damage repair, transcription and replication. Therefore, the family of these crucial proteins can be valuable targets for drug development and treatment of many diseases, mainly of bacterial and viral in nature, as well as cancers. For example, DNA polymerases and reverse transcriptases can be used as molecular targets for antiviral and antitumor chemotherapy. genomic dna vs cdna library https://comlibrary.bocsci.com/services/dna-and-rna-polymerase-screening-library.htm
