The success of cloning experiments led to all of the following conclusions EXCEPT:
A)the transcriptional state of a differentiated cell is reversible
B)the transcriptional state chromatin in a differentiated cell is irreversible
C)the transcriptional state chromatin in a differentiated cell is reversible
D)a nucleus from a differentiated cell can be reprogrammed by factors residing in the cytoplasm of its new environment

Question

Quizplus · Accepted Answer

The success of cloning experiments suggests that the transcriptional state of chromatin in a differentiated cell is reversible and that a nucleus from a differentiated cell can be reprogrammed by factors in its new environment. These conclusions were demonstrated by successful cloning experiments using somatic cells, such as the production of Dolly the sheep. However, the experiments did not conclude that the transcriptional state of chromatin in a differentiated cell is irreversible, as some cells can be reprogrammed through various methods such as induced pluripotent stem cells (iPSCs). Therefore, option B is the only incorrect option.
