Because the experimental design can be done before the program designed for individuals to access, such as by using cadnano dna database available to reduce the cost.
Because of the design can be done prior to the actual trial, through a program that uses the common person to design accessible like CADNano etc using the existing DNA database as a cost reduction.
Due to the design can be made before the actual trial through the program to design a general person can be accessed such as CADNano DNA, etc. by using the existing database is to reduce the cost of the
