Answer:
Direct DNA sequencing
Step-by-step explanation:
Direct DNA sequencing is the type of genetic testing which is the most sensitive method for detecting any mutation in a specific gene.
DNA sequencing is a critical biological method that is used in laboratories to determine the accurate order of nucleotides, along the chromosomes and genomes.
With the help of this method, we are capable of investigating a number of diseases and genetic illnesses along with the detection of mutation in any gene.
