Answer
The steps in nuclear transplantation are as follows:
Solution
a
Donor Cell Extraction: A somatic cell is taken from the organism that is to be cloned. This cell contains the complete set of DNA required for the new organism
b
Enucleation: The nucleus of an egg cell (oocyte) is removed, creating an enucleated egg cell. This step is crucial as it ensures that the egg cell will only contain the DNA from the donor cell
c
Nuclear Transfer: The nucleus from the donor cell is inserted into the enucleated egg cell. This can be done through a process called cell fusion or direct nuclear injection
d
Activation: The egg cell, now containing the donor nucleus, is stimulated to begin dividing and developing into an embryo. This can be achieved through chemical or electrical stimulation
e
Embryo Development: The activated egg cell divides and develops into an embryo. This embryo is then implanted into a surrogate mother, where it can develop into a full organism
Key Concept
Nuclear Transplantation
Explanation
Nuclear transplantation involves transferring the nucleus from a donor cell into an enucleated egg cell, which is then stimulated to develop into an embryo. This technique is used in cloning and research to study developmental biology.
