Questions and Answers
What is a clone?
What is a clone?
- A group of identical cells or organisms produced from a cloning experiment (correct)
- A group of genetically modified cells or organisms
- A group of similar cells or organisms produced from a cloning experiment
- A group of cells or organisms with different genetic makeup
How can some plants be cloned?
How can some plants be cloned?
- By taking cuttings (correct)
- By using genetic modification techniques
- By altering their DNA sequences
- By exposing them to certain chemicals
What is required to clone a gene?
What is required to clone a gene?
- Exposing it to radiation to induce mutations
- Altering its genetic sequence using CRISPR technology
- Inserting it into a vector that can carry the gene into a host cell and ensure its replication (correct)
- Transferring it directly from one organism to another

Study Notes
Cloning
- A clone is an exact genetic replica of an organism or a DNA sequence
Plant Cloning
- Some plants can be cloned through vegetative propagation, where a new plant grows from a part of the parent plant
Gene Cloning
- To clone a gene, the following is required:
- A DNA molecule containing the gene of interest
- A vector (e.g. plasmid) to carry the gene
- A host organism (e.g. bacterium) to express the gene
- Restriction endonucleases to cut the gene and vector
Frog Cloning
- In 1962, John Gurdon produced clones of identical frogs by transplanting nuclei from a single frog embryo to many enucleate eggs
Discovery of Restriction Endonucleases
- In the late 1960s, Werner Arber and Hamilton Smith discovered restriction endonucleases in E. coli, which revolutionized molecular biology
