How is recombinant DNA made?

• by joining DNA molecules with RNA molecules

• by joining DNA molecules from two different species

• by joining DNA molecules with proteins from a different species

• by joining DNA molecules from two chromosomes of the same organism

Which is one reason scientists produce transgenic organisms?

• to create new species of organisms

• to control microorganisms in the soil

• to prevent habitats from being destroyed

• to treat certain types of diseases

How can gene therapy positively impact society?

• by producing insulin using bacteria

• by creating fingerprints of criminals

• by mapping all genes in the human population

• by treating genetic disorders with the insertion of normal genes

Which statement best describes the relationship between genes and the environment in determining traits?

• Genes completely determine traits, and the environment has no effect

• The environment determines traits, and genes have no role

• Genes provide instructions for traits, and the environment can influence how those traits appear

• Traits are caused only by random chance

A student has the genes for tall height but grows up with poor nutrition. What is the most likely outcome?

• The student will grow taller than average

• The student’s height may be shorter than their genetic potential

• The student’s genes will change due to nutrition

Why do identical twins sometimes have different appearances or health outcomes?

• They have different genes

• One twin has mutations that the other does not

• Environmental factors can affect how their genes are expressed

• Traits are not controlled by genes
