scientists hypothesize that the mutant mouse from the previous question has a mutation in gene z that affects the gene expression of gene z in the brain. scientists extract rna from the brain (glial and neural cells) of the mutant mouse and wild type mice. they analyze gene expression of gene z on an rna gel. predict how the mutant mouse gene expression will compare to the wild type. if needed in your answer, include information about the location of the band and/or size/intensity of the band. briefly explain your answer.
