______ _______ is the use of genetic en- gineering to correct the defective genes responsible for certain diseases. Scientists inject a corrected gene into a person suffer- ing from the disease. I
Gene Therapy. (Done to correct defective genes)
Using special techniques to control the genetic makeup of an organism is called ______ ________.
Genetic engineering
In _______ _______, man chooses animals/plants with desirable traits and breeds them, hoping that their offspring will have those same traits
Selective breeding
_______ is the mating of an organism with its close relatives.
Inbreeding
________ involves breeding individuals from different varieties to try to produce offspring that have the traits of BOTH parents.
It is very difficult and expensive because each offspring produce unique results
Crossbreeding
For example, a variety of wheat that survives cold temperatures is bred with another variety of wheat that resists a certain fungal disease. The offspring, called Marquis (MAR kwis) wheat, has both of these traits. Marquis wheat is more likely to survive both cold temperatures and fungal disease than its parent plants are.
Give two examples of how Genetic engineering can cause serious problems:
scientist makes a mistake while working with a virus, might form a disease organism that could destroy many living things
A genetically engineered plant might grow so well that it becomes a weed problem
For an alternarive form of energy, Studies show that ______ produces about four times more energy than is used during the production and purification processes. This is a much better ratio than the plant-based biofuels (corn) discussed in Chapter 4
Algae
Does creating a genetically perfect human solve man’s problems or not? Why?
no technological or medical advancement will ever solve man’s ultimate problem—the problem of sin.
A _______ is a complete set of an organism’s genes.
Genome
How many genes were in the Human Genome Project? What is good and bad about this project?
20,000–25,000 genes
Good: fix diseases
Bad: abort non-perfect babies
It’s ok to experiment with plants/animals… But why is it different with changing human genetics?
What is one way that genetic engineering is already being used to treat disease in humans?
Example: inserting genes that create insulin into bacteria to create insulin.
(True or False) The Human Genome Project identified the genes that code for every trait in the human body.
False. Almost there
