One of the main obstacles to successful cloning of sheep, apparently overcome by Wilmut et al., was:
A) to find an adult nucleus that was likely to work.
B) to synchronize the cell cycles of the donor cell and the egg cell.
C) to enucleate the donor cell.
D) the ability to culture cells in the laboratory.
E) to recognize that the nucleus from one sheep cell may contain different genetic information than the nucleus of another cell from the same animal.
Cloning Sheep
The process of creating a genetically identical copy of a sheep by manipulating its DNA.
Cell Cycles
The cell cycle is the series of events that take place in a cell leading to its growth, replication, and division into two daughter cells.
Donor Cell
A cell that provides genetic material to another through processes such as transplantation, transfusion, or genetic engineering.

Final Answer :
B
Explanation :
The main obstacle overcome by Wilmut et al. in the successful cloning of sheep was to synchronize the cell cycles of the donor cell and the egg cell. This synchronization is crucial for the successful development of the cloned embryo.
