Genetic Technologies

Which of the following statements is true of all genetically engineered organisms?

• They have a genome that is identical to their parents’ genome.

  
  

• They are made using half the genomes of two different species

• They contain genes transferred from another organism.

• They are produced by breeding only the individuals with desired traits

Genetic technologies are in the news now almost every day. Scientists, engineers, animal breeders, farmers, doctors, and police use genetic techniques to answer questions, grow food, prevent illness, and solve crimes. Read each sentence in the right column that describes a problem that can be solved with genetic technology. Then draw lines to match each genetic technology in the left column with an example of a problem it can solve in the right column

(d) Artificial Selection

• A child is born with a faulty gene that causes a serious disease.

• Scientist want to breed larger cows for larger quantities of meat.

• A racehorse owner wants to make an exact copy of his champion horse.

• Scientists transfer a fluorescent gene from a jellyfish into a fish to study chemicals in bodies

When an organism is genetically engineered, what occurs?

• the genome is identical to their parents'

• they are made using half the genomes of two different species

• the organism contains genes that were transferred from another organism

• they are produced by breeding only the individuals with desired traits.

What is gene therapy?

• A process in which modern geneticists can transfer a gene from the DNA of one organism into another.

• A process of changing a gene to treat a medical disease or disorder.

• A process of creating clones with the same genes as the organism from which they were produced.

• A process of selectively breeding organisms with desired traits.
