Genetic Engineering

What is Genetic Engineering?

• the manipulation of an organism’s genes
• a change in an organism's genes
• a random and abrupt disruption to DNA
• the manipulation of an organism's appearance

Humans have experimented with genetic engineering ________.

• a long time
• only recently
• only in science fiction novels

In this class, we will study what type of genetic engineering?

• Genetic Modification
• Genetic Duplication
• Recessive Breeding
• Selective Breeding

What is selective breeding?

• A process in which mates pick which partner to have offspring with
• It is a process humans use to breed or reinforce desired traits into a particular organism.
• A process to get rid of beneficial traits
• A process to add harmful traits

What is an example of selective breeding by farmers?

• Mating 2 small chickens to create more large chickens
• Mating 2 large chickens to create more large chickens
• Mating 2 large chickens to create more small chickens
• Using a machine to change the DNA of a chick

Scientists and historians generally agree that humans began selective breeding because

• To find reliable, predictable sources of food
• To become better at science
• They were lazy
• They were going extinct from predators.

What is one reason why people are against genetic engineering?

• There is a high risk of failure
• It has a 100% success rate
• People do not like dogs

Based on the notes, how can technology help with genetic engineering?

• it can be used to add, or modify genes directly into living things.
• It can prevent disorders with a 100% success rate
• It can cause birth defects
• It has no ethical issues

Scientists genetically engineer corn to be immune to corn diseases. This is BENEFICIAL because

• This causes corn to be less likely to reproduce
• This causes corn to be less likely to survive
• This causes corn to be smaller
• This allows increased production of corn
