3. Which of the following statements about somatic cloned embryonic stem cells is correct?
① It is extracted from embryos like embryonic stem cells.
② Differentiation proceeds through the replication process and is extracted as differentiated cells.
③ There is an immune rejection reaction.
④ Reproduction is possible using heterogeneous somatic cells.
⑤ Somatic cell cloning In order to obtain embryonic stem cells, it is necessary to extract the nucleus of the egg.
4. Choose the wrong one in the description of the embryonic stem cell extraction process.
