How Mutations Affect DNA

What do mutations cause in DNA?

Mutations cause changes in DNA which ultimately changes _____.

A. elements

B. proteins

C. compounds

D. essential nutrient

Answer:

The correct answer is B. proteins.

Mutations are changes in the DNA sequence that can affect genes and proteins. These changes can lead to different traits or characteristics in organisms. When mutations occur, they can alter the way proteins are made, which can have various effects on an organism.

Proteins play essential roles in the body, acting as enzymes, hormones, antibodies, and structural components, among other functions. Therefore, changes in proteins due to mutations can impact the overall functioning of an organism.

Understanding how mutations affect DNA and proteins is crucial in fields such as genetics, medicine, and evolutionary biology. By studying these changes, scientists can gain insights into genetic disorders, diseases, and even natural selection processes in different species.
