What is a plasmid in the context of genetic cloning?
Click to flip
A plasmid is a small, circular DNA strand in bacteria used as a vector for genetic cloning.

Who was the first scientist to successfully clone an animal?
Click to flip
Dolly the sheep was the first mammal to be cloned from an adult somatic cell by Ian Wilmut and Keith Campbell.

What is therapeutic cloning?
Click to flip
Therapeutic cloning aims to create tissues or organs for transplantation to treat disease.
Click to flip
What is reproductive cloning?
Click to flip
Reproductive cloning creates an organism that is genetically identical to the donor organism.
Click to flip
Why is the enzyme reverse transcriptase important in cloning?
Click to flip
Reverse transcriptase transcribes RNA into DNA, which is useful in cloning eukaryotic genes.
Click to flip
What role does the enzyme ligase play in genetic cloning?
Click to flip
Ligase is used to join DNA fragments together, completing the insertion of foreign DNA.
Click to flip
What is the significance of the Human Genome Project to genetic cloning?
Click to flip
The Human Genome Project mapped all human genes and helped advance techniques in genetic cloning.
Click to flip
What ethical concerns are associated with genetic cloning?
Click to flip
Ethical concerns include the potential for misuse, identity issues, and impacts on biodiversity.
Click to flip
What is DNA sequencing and why is it important to cloning?
Click to flip
DNA sequencing determines the order of bases in DNA, crucial for understanding and replicating genes.
Click to flip
How can cloning be used in medicine?
Click to flip
Cloning can lead to advances in gene therapy and the production of genetically identical organisms for study.
Click to flip
What is gene cloning's potential role in agriculture?
Click to flip
Gene cloning can produce crops with desirable traits like pest resistance and higher yields.
Click to flip
Why might cloning not always produce a perfect copy?
Click to flip
Environmental factors and epigenetic changes can influence the development of clones, affecting their traits.
