A researcher has used in vitro mutagenesis to mutate a cloned gene and then has reinserted the mutated gene into a cell. To have the mutated sequence disable the function of the gene, what must then occur

recombination resulting in replacement of the wild type with the mutated gene

Explanation:

Recombination is a process of the formation of new alleles when the original ones are broken down into bits and then ‘recombined’.

When mutation of a cloned gene occurs and the mutated gene is reinserted into a cell, the mutated sequence gene function will have to be disabled which involves recombination resulting in replacement of the wild type with the mutated gene.

i think that c)gold was found there

but i am not sure

most community's take hundreds of years to become stable
