Then the nucleus of a cell -- any cell in the body -- is taken from the individual to be cloned and inserted into the egg.
The adult cell whose nucleus was transferred into the egg that became Dolly had a male imprinted genome that was inherited at birth and copied to every cell of the donor's body.
When I attempted to cut the towering almond meringue topping into wedges, the knife sank ominously into the baked egg whites instead of casting shards of crunchy meringue.
But all of the embryos will be exposed to the Medea effect, because it comes into the embryo through the egg, which was created by the Medea-carrying mother.
She cracked the first egg into the pool of fat she made by tilting the pan.
Soon after spawning, the egg membranes undergo chemical reactions that seal the pores that let water into or out of the egg.
The second thing the team did was to introduce a genetic mutation into the genome of the young egg that allowed for the production of a growth factor, a kind of protein, that can only come from the paternal genome but is vital for normal embryonic development.
Reproductive cloning, which created Dolly the sheep in 1997, involves transferring the nucleus of an adult cell into an egg, giving the resulting embryo a full set of genes without the normal sperm-meets-egg fertilisation step.
The researchers said this is a way of getting more specific genetic material into an egg than the method used on Dolly.
Putting only one fertilised egg into the womb avoids multiple births, which are known to increase the health risks of both mother and child.
According to the medical definition, pregnancy doesn't begin until a fertilized egg implants itself into the wall of the uterus.
Fold egg whites into the batter.

In the cloning experiment, cells from an infertile father would be injected into an egg, which is then implanted in the mother's uterus for the pregnancy.
Only your fists, power-ups, and the occasional giant egg (which transforms you into a gnome or transfer you to the back of a laser-breathing dinosaur) can keep you running.
FORBES: 'Punch Quest' Review - A Running, Punching Good Time
And they've been forced to eat into a nest egg designed to support the girls as adults.
The cell is then given a jolt of electricity to activate cell division, basically tricking the cell into doing what a fertilized egg would normally do.
It wasn't until later that afternoon, when our friends cut into the cake, that we realized that the seeping liquid wasn't just raw egg whites, but raw batter as well.
It recommends that in the acute stages the disease can be cured by cutting into the normal flesh around the cancer, cauterising the wound and then sealing it with egg yolk before washing it with wine.
Making small but regular payments into appreciating assets can form the basis of a rainy day fund or even grow into a sizable nest egg over time.
Funny as it may seem now, the egg business was a bridge into the trading world.
They break down into pieces that thicken the dish much like an egg does in a carbonara.

Sir Ian and his team fused the genetic information from an adult sheep cell nucleus with an egg cell to form an embryo that developed into a genetically identical copy of the original adult.
Certainly, something unusual is happening in the process by which the egg cell sends out signals to reprogram its new nucleus and put the developmental genes back into action.
His method involves inserting the nucleus from an egg with faulty mitochondria into a donor egg that has had its nucleus removed.
FORBES: UK May Be Close To Approving Nuclear Transfer Technique for IVF
Scientists say DNA taken from a cell in the ovary of an adult camel was put into an egg from a surrogate mother.
Dan and Scott Shillum are identical twins, genetic clones produced from the accidental division of a single fertilised egg into two embryos in their mother's womb some 40 years ago.
Ethicists on the left have worried that it might turn women into egg-production factories.
All leftover funds roll over into the next year, allowing employees to build a nice nest egg over time.
