细胞质细胞器中极高的基因组拷贝数是细胞生物学中一个令人费解的事实。这里提出，高拷贝数反映了对细胞器核糖体的需求增加，而只有通过基因组复制导致的核糖体RNA基因数量的增加才能满足这一需求。
The very high genome copy number in cytoplasmic organelles is a puzzling fact in cell biology. It is proposed here that high copy number reflects an increased need for organellar ribosomes that can only be satisfied by the increased ribosomal RNA gene number that results from genome multiplication.
