Multiple Choice

Which of the following statements best describes the role of genetic information in the development of genetic diseases?

Genetic information is unrelated to the inheritance of genetic diseases and only affects environmental responses.

Genetic information determines the sequence of amino acids in proteins, and mutations in this information can lead to malfunctioning proteins that cause genetic diseases.

Genetic information is stored in carbohydrates, which are responsible for most genetic diseases.

Genetic information only affects physical traits and does not influence the risk of developing genetic diseases.

Verified step by step guidance

Understand that genetic information is encoded in DNA, which contains the instructions for building proteins through the sequence of nucleotides.

Recognize that proteins are made up of amino acids, and the specific sequence of amino acids determines the protein's structure and function.

Know that mutations are changes in the DNA sequence that can alter the amino acid sequence of a protein, potentially leading to a malfunctioning or nonfunctional protein.

Connect that malfunctioning proteins caused by mutations can disrupt normal biological processes, which may result in genetic diseases.

Conclude that genetic information is crucial because it determines protein structure, and mutations in this information are a primary cause of genetic diseases.
