Cloning

Clones have the exact same:

• Personalities

• Physical appearances

• Intelligence levels

• Genetic material

What can you conclude from the fact that humans have cloned plants for thousands of years?

• Most of the crops that exist today are clones

• Cloning plants is much easier than cloning animals

• Cloned plants are immune to all diseases and pests

• Much of today's modern technology was developed in ancient times

What was the significance of Dolly the Sheep?

• She was the first organism ever cloned

• She was the first clone created from an adult animal

• She was the first animal cloned as an embryo

• She was the first animal to be cloned multiple times

Why would scientists want to clone cows?

• To produce more cows at a faster rate

• To produce adult cows instead of calves

• To produce stronger and healthier livestock

• To replace chickens and goats, which are harder to clone

How might cloning eventually help humans live longer?

• Clones tend to live longer than the parent organism

• Cloned human organs could replace unhealthy ones

• By being cloned multiple times, a person could essentially live forever

• The food obtained from cloned organisms would be healthier than ordinary food

How did Dolly compare to sheep that were cloned with the same DNA?

• Dolly lived longer

• Dolly had more genetic material

• Dolly was less healthy

• Dolly had fewer parents

A crop of plants is more likely to survive a deadly virus if the plants:

• Have unique DNA

• Are planted close together

• Receive little sunlight

• Are cloned from the same plant

Which of the following is an ethical question about cloning?

• Can a human clone ever lead a fulfilling life?

• How can DNA be removed from adult animal cells?

• What will happen to crop yields if cloned plants develop a virus?

• Is human cloning scientifically possible?
