For fill-in-the-blank questions, complete the sentence with the appropriate term. For short-answer questions, provide concise and accurate responses.
1. What is the primary purpose of reproductive cloning?
To produce genetically identical copies of an entire organism.
To create tissues and organs for medical treatment.
To study genetic diseases in embryos.
To develop new agricultural crops.
2. Which of the following is a key step in somatic cell nuclear transfer (SCNT)?
Fertilizing an egg cell with sperm.
Injecting DNA directly into a zygote.
Removing the nucleus from an egg cell.
Fusing two somatic cells together.
3. The process of creating a genetically identical copy of a gene, cell, or organism is known as .
4. In therapeutic cloning, the goal is to produce cells for medical purposes, not a complete organism.
5. Dolly the sheep was the first mammal successfully cloned from an adult cell.
