Changes in the free and membrane-bound ribosomes in maternal rat liver during starvation.


Free and membrane-bound ribosomal ribonucleic acid (RNA) from maternal rat liver was measured in virgin rats and in variously dated pregnant animals that were either fed or starved for one to four days. The total amounts of free and membrane-bound ribosomal RNA differed between pregnant and nonpregnant rats, but the free ribosomal RNA progressively… (More)
