How do we target specific genes in pcr

WebApr 12, 2024 · The main cause of ADO is the failure of primers to anneal and amplify the target location either by sequence alteration in the target sequence or by suboptimal PCR conditions. Let’s understand each scenario, one after another. Genetic alteration: Sequence variation or mutation in any of the alleles of the target sequence cause allelic dropout. WebGene targeting (also, replacement strategy based on homologous recombination) is a genetic technique that uses homologous recombination to modify an endogenous gene.The method can be used to delete a gene, remove exons, add a gene and modify individual base pairs (introduce point mutations).The process of gene targeting provides a way to alter …
