nuclear transplantation
Học thuậtThân thiện
Definition
Noun: - Moving a cell nucleus and its genetic material from one cell to another: A scientific procedure where the nucleus containing the genetic material (DNA) is removed from one cell and transferred into another cell, typically an egg cell that has had its own nucleus removed. This process is fundamental to cloning and certain types of stem cell research.
Usage Examples
- Noun:
- The successful nuclear transplantation in the lab created an embryo that was a genetic copy of the donor.
- Scientists are studying nuclear transplantation to understand cellular reprogramming.
- Ethical debates often surround the use of nuclear transplantation for potential human cloning.
Advanced Usage
- "Somatic cell nuclear transplantation (SCNT)": A specific and common type of nuclear transplantation where the nucleus from a somatic (body) cell is transferred into an enucleated egg cell.
- Dolly the sheep was created using a technique called somatic cell nuclear transplantation.
Variants and Related Words
- Nuclear transfer: A synonymous term often used interchangeably with nuclear transplantation.
- Cloning: The broader process of creating a genetically identical copy of an organism, for which nuclear transplantation is a key technique.
- Enucleation: The process of removing the nucleus from a cell, which is a preparatory step in nuclear transplantation.
Synonyms
- Nuclear transfer
- Somatic cell nuclear transfer (SCNT)
Related Phrases
- Therapeutic cloning: The application of nuclear transplantation to create embryonic stem cells for medical research and potential therapies.
- The goal of therapeutic cloning via nuclear transplantation is to generate patient-specific cells for treatment.
Noun
- moving a cell nucleus and its genetic material from one cell to another
