Evolution, Selective Breeding, and Genetic Engineering

Front

What is genetic engineering?

Back

Genetic engineering is the process of changing the genetic sequence of a DNA strand so that a particular trait is produced.

Front

What is the main goal of genetic engineering?

Back

The main goal of genetic engineering is to use technology to cut DNA and insert genes to obtain desired traits.

Front

What is artificial selection?

Back

Artificial selection is the process by which humans choose individuals with desirable traits to parent the next generation.

Front

How does natural selection differ from artificial selection?

Back

In natural selection, traits benefit the species, while in artificial selection, the traits benefit humans.

Front

What is an example of genetic engineering?

Back

Inserting a gene for bioluminescence (glowing) into fish is an example of genetic engineering.

Front

What is the role of DNA in genetic engineering?

Back

DNA contains the genetic information that can be modified to produce specific traits in organisms.

Front

What is selective breeding?

Back

Selective breeding is the process of breeding plants or animals for specific traits, guided by human choice.

Front

What is the significance of the wolf in dog breeds?

Back

Evidence shows that the wolf is the ancestor to all dog breeds, and their variation arose through artificial selection.

Front

What is the outcome of genetic engineering?

Back

The outcome of genetic engineering can be the creation of organisms with new traits that do not occur naturally.

Front

What is the difference between natural selection and genetic engineering?

Back

Natural selection occurs naturally over time, while genetic engineering is a human-directed process.
