DNA Structure and Function Quiz

What is the evidence provided in the text to support the claim that DNA serves as the blueprint for life?

• DNA contains all the instructions needed to build and maintain an organism.

• DNA is made up of smaller units called nucleotides.

• The components of DNA are arranged in a double helix structure.

• The specific sequence of bases along the DNA molecule determines the genetic code of an organism.

According to the text, what is the role of amino acids in determining an organism's traits?

• Amino acids determine the structure and function of DNA.

• Amino acids form the sides of the DNA ladder.

• Amino acids are the building blocks of proteins.

• Amino acids code for specific nucleotides.

What is the main idea of this passage?

• DNA is a molecule found in every living organism.

• Scientists have different theories about the origins of DNA.

• Understanding DNA is crucial for unraveling the mysteries of life.

• DNA consists of nucleotides and nitrogenous bases.

What are the four nitrogenous bases in DNA?

• Adenine, Thymine, Cytosine, Guanine

What role do proteins play in your own body and everyday life?

• Proteins provide energy for the body.

• Proteins are involved in DNA replication.

• Proteins are the building blocks of cells.

• Proteins regulate body functions and carry out chemical reactions.

Why do you think scientists are still investigating the origins of DNA? How does this impact our understanding of life?

• Scientists are curious about the origins of DNA, but it does not impact our understanding of life.

• Scientists are trying to find evidence for the theory of spontaneous generation.

• Understanding the origins of DNA can provide insights into the evolution of life on Earth.

• Understanding the origins of DNA can help scientists create new organisms.

What is the function of phosphate groups in DNA?

• Phosphate groups determine the genetic code of an organism.

• Phosphate groups form the sides of the DNA ladder.

• Phosphate groups help to link nucleotides together in DNA and RNA.

• Phosphate groups code for specific amino acids.
