Traits, heredity, and genetics

Front

What is DNA?

Back

DNA (deoxyribonucleic acid) is the molecule that carries the genetic instructions for life. It is made up of two strands that coil around each other to form a double helix.

Front

What is a trait?

Back

A trait is a characteristic or feature of an organism, such as eye color, height, or personality.

Front

What is heredity?

Back

Heredity is the passing of traits from parents to their offspring through genes.

Front

What are genes?

Back

Genes are segments of DNA that contain the instructions for building proteins, which determine the traits of an organism.

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence that can lead to changes in traits. Mutations can occur naturally or be caused by environmental factors.

Front

What is the role of RNA in genetics?

Back

RNA (ribonucleic acid) plays a crucial role in translating the genetic information from DNA into proteins.

Front

What is genetic material?

Back

Genetic material is the substance that carries genetic information in living organisms, primarily DNA.

Front

What are environmental factors that can cause mutations?

Back

Environmental factors include radiation, chemicals, and viruses that can damage DNA and lead to mutations.

Front

What is the difference between beneficial and injurious mutations?

Back

Beneficial mutations provide an advantage to the organism, while injurious mutations can harm the organism or reduce its chances of survival.

Front

What is the significance of genetic diversity?

Back

Genetic diversity is important for the survival of a species as it allows for adaptation to changing environments.
