BP- Cloning

1. 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?

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

• Cloned plants are immune to all diseases and pests

• Cloning plants is significantly easier than cloning animal

• Most of the crops that exist today are clones

What was the significance of Dolly the Sheep?

• She was the first organism ever cloned

• She was the first animal cloned as an embryo

• She was the first adult animal to be cloned

• She was the first animal to be cloned multiple times

Why would scientists want to clone cows?

• Cows don't reproduce quickly enough to meet the demand for meat and dairy products

• To create livestock that are almost guaranteed to be strong and healthy

• Raising calves is expensive and time-consuming; cloning cows would produce adult animals ready for slaughter

• Cows are much easier to clone than animals like chickens and goats

How might cloning eventually help humans live longer?

• Cloned human organs could be used to replace unhealthy ones

• Clones tend to live longer than the organisms they take their DNA from

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

• The food obtained from cloned animals and plants would be healthier and more life-sustaining than ordinary food

Tim says that genetic diversity helps species survive. What is genetic diversity?

• When many different species live together in one particular environment

• When an organism's DNA changes throughout its lifespan

• When a population of organisms contains a wide range of genetic traits

• When organisms are able to trade pieces of DNA with one another

Which of the following is an example of an ethical question?

• How can DNA be removed from adult animal cells?

• Can a human clone ever lead a fulfilling life?

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

• Is human cloning scientifically possible?

In what decade was Dolly the cloned sheep born?

• 1970s

• The 1980s

• The 1990s

• The 2000s
