Examples

• Scientists created a cytoplast by carefully removing the nucleus from the egg cell.
• The cytoplast retained most of the cell's metabolic functions despite lacking a nucleus.
• In cloning experiments, researchers fused a nucleus with a cytoplast to create a new embryo.
• The cytoplast's cytoplasm continued to support protein synthesis and other vital processes.
• Researchers studied how long a cytoplast could survive without nuclear control.
