Chromosomes are not visible when there is no cell division. It cannot be seen
in the cell’s nucleus nor under the finest microscope. They are only visible
when the cell is dividing and is apparently visible under a microscope.
I rerun this most-read post about when human life begins every time that the discussion resurges, which is usually in the shadow of proposed restrictions on women’s reproductive rights. Strong feelings always seem to trump biological facts. Confusion among politicians appears to be apparent concerning when certain events begin or structures appear; whether to track development from fertilization (conception) or the last menstrual period; and even the distinction between an embryo and a fetus.
