Question 1 of 10
1 of 10
The last giant Galapagos tortoise died in 2012. Scientists froze some of the tortoise’s cells.
These statements describe processes involved in potential cloning of the giant Galapagos tortoise using the cells. They are not in the correct order.
1 - a donor egg is enucleated
2 - the embryo develops into a mature egg, which is incubated
3 - a somatic cell from the tortoise is defrosted and the nucleus is removed
4 - electrofusion of the host cell and new nucleus
5 - the somatic cell nucleus is inserted into the enucleated oocyte
6 - the transformed egg divides in vitro
Which option states the correct order for producing a clone of the giant Galapagos tortoise?
