In Amoeba proteus the transplantation of a nucleus engaged in DNA synthesis into a G(2)-phase (after DNA synthesis) cell results in inhibition of such synthesis. When the nucleus of a G(2) cell is transplanted into an S-phase (period of DNA synthesis) cell, such a nucleus may begin to synthesize DNA.
在变形虫中,将处于DNA合成阶段的细胞核移植到G2期(DNA合成之后)的细胞中,会导致这种合成受到抑制。当将G2期细胞的细胞核移植到S期(DNA合成期)细胞中时,这样的细胞核可能会开始合成DNA。
