What is the primary function of a gene?

• To replicate cells

• To transport nutrients

• To store energy

• To encode a specific protein

Where is a gene specifically located?

• In a chromosome

• In the mitochondria

• In the cell membrane

• In the cytoplasm

Which of the following statements is true about gene location?

• Genes are defined by their location in a chromosome

• Genes are found in the cell wall

• Genes are located in the nucleus

• Genes are randomly scattered in the body

How are most characteristics in an organism determined?

• By random chance

• By a single gene

• By environmental factors only

• By many different genes working together

Which characteristic is sometimes determined by a single gene?

• Intelligence

• Eye color

• Weight

• Height
