单项选择题
What is the logical order of the following paragraph?
"The cloning of Dolly involved several steps. First, cells that had previously been taken from Dolly's mother were starved for five days, which caused them to stop dividing. This interruption of the cells' division cycle made it easier for them to reprogram themselves to start growing a new organism. After five days, the nuclei of these cells were removed and transferred into an unfertilized sheep egg, from which the natural nucleus had previously been removed. In the next step, the egg was grown in the laboratory for a period of time. Then the egg was implanted into a different sheep, where it grew normally. When the sheep finally gave birth, the lamb was an exact genetic copy, or clone, of the sheep that had provided the transferred nucleus, not of the sheep that had provided the egg."
