Ashley donated a regular body cell and Jesse donated an egg cell. Jesse’s egg cell had its nucleus removed. Ashley’s cell nucleus was transferred from the body cell into the egg cell. Cell division occurred and the new embryo was implanted into Madison, the surrogate mother. Madison eventually gave birth to the baby. Who does the baby resemble?
Ashley

If a restriction enzyme cuts at the sequence CC/GG what kind of ends would we end up with on the DNA fragments?
Blunt Ends

EcoRI recognizes the following sequence: G A A T T C C T T A A G
What types of ends would this cut result in?
Sticky
