Modern Cloning Techniques

The video tutorial explains cloning in science, highlighting that clones are organisms with identical DNA. It covers plant cloning methods like cuttings and tissue culture, and animal cloning techniques such as embryo cloning and adult cell cloning, exemplified by Dolly the sheep. The video also discusses ethical concerns surrounding cloning, particularly the potential for human cloning and associated rights issues.

What is the primary reason a gardener might use cuttings to clone plants?

• To create genetically diverse plants

• To produce plants with different characteristics

• To quickly and cheaply produce identical plants

• To experiment with new plant species

In embryo cloning, why are surrogate cows used?

• To provide genetic material for the embryos

• To carry and develop the embryos until birth

• To ensure the embryos have diverse DNA

• To increase the milk production of the calves

What is a potential downside of embryo cloning in animals?

• The calves may not have the desired traits

• The process is too quick and inexpensive

• It results in genetically diverse offspring

• The surrogate cows become clones themselves

What was significant about Dolly the sheep?

• She was the first mammal cloned from an adult cell

• She was cloned using plant tissue culture techniques

• She was the first animal to be cloned using embryo cloning

• She was the first clone to live over 10 years

What is a major ethical concern regarding human cloning?

• The reduction in the number of surrogate mothers needed

• The ability to clone plants more efficiently

• The destruction of embryos during the process

• The potential for increased genetic diversity
