Multiple Choice

Which molecule contains instructions for making everything a cell needs?

• Protein

• RNA

• DNA

• Enzyme

Multiple Choice

What is gene expression and why is it important for cells?

• It is the process of copying DNA into RNA and is important for cell division.

• It is the process that turns genetic instructions into action, controlling cell types, responses to the environment, growth, and repair.

• It is the process of making proteins from amino acids and is important for energy production.

• It is the process of cell death and is important for removing damaged cells.

Multiple Choice

What role do transfer RNA (tRNA) molecules play during translation?

• They bring specific amino acids to the ribosome to build proteins.

• They copy the DNA code into mRNA.

• They transport proteins out of the cell.

• They break down mRNA after translation.

Multiple Choice

Why is accurate gene expression and protein synthesis essential for normal development and health?

• Because errors can cause nonfunctional proteins and lead to disease.

• Because it increases the speed of cell division.

• Because it allows cells to store more energy.

• Because it helps cells move faster.
