Mutations
Explore how mutations—changes in a DNA nucleotide sequence—can result from copying errors or environmental factors. Understand how mutations alter protein structure and function, influencing traits. Describe harmful mutations that cause disorders, beneficial mutations that improve survival, and neutral mutations that have no observable effect on an organism’s health or traits.
