Once bound to their target DNA sequence, the ZFNs cut the genome at the specified location, allowing scientists to either delete the target DNA sequence or replace it with a new DNA sequence via homologous recombination.
WebJun 8, 2024 · The first step is to recreate the original DNA template strand (called cDNA) by applying DNA nucleotides to the mRNA. This process is called reverse transcription. This requires the presence of an enzyme called reverse transcriptase. After the cDNA is made, regular PCR can be used to amplify it.
