gigi gigi gigi gigi gigi gigi gigi gigi gigi gigi gigi



for thegenetic material. Why?
gigi gigi gi gigi gigi



Answer: Proteins are the most abundant, universally distributed components in cells. gigi gigi gigi gigi gigi gigi gigi gigi gigi



Becauseof their great structural and functional diversity, they were considered likely
