Genes influence an organism's traits by coding for proteins.

Front

What are the building blocks of DNA compared to?

Back

The building blocks of DNA are like alphabet letters because they spell out different instructions depending on their order.

Front

How do mutations impact natural selection?

Back

Mutations affect how likely an organism is to survive and reproduce.

Front

What is the difference between editing the genetic code and artificial selection?

Back

Editing the genetic code enables humans to directly change DNA.

Front

What does a gene carry for a trait?

Back

A gene carries the instructions for a trait.

Front

What is DNA?

Back

DNA (deoxyribonucleic acid) is the molecule that carries the genetic instructions for life.

Front

What is a mutation?

A mutation is a change in the DNA sequence that can lead to changes in traits.

Front

What is natural selection?

Back

Natural selection is the process where organisms better adapted to their environment tend to survive and produce more offspring.

Front

What is artificial selection?

Back

Artificial selection is the process by which humans breed specific plants or animals for desired traits.

Front

What role do proteins play in an organism?

Back

Proteins perform a variety of functions in the body, including building tissues and facilitating biochemical reactions.
