Through these experiments, you concluded that:

1. Mutations in DNA can lead to changes in the amino acid sequence of a protein. Changes in amino acid sequence can cause changes to protein structure. Changes in protein structure may cause changes in function. If a protein cannot function properly, some of the functions of the organism may be affected because the functions of an organism often depend on the functions of the proteins within the organism. However, not all mutations cause changes in an organism. Some mutations in DNA do not cause changes in the amino acid sequence of a protein and therefore do not change a protein’s structure or function. Some mutations in DNA cause changes in amino acid sequences without changing the structure and function of a protein. Some mutations cause changes in the structure of a protein without affecting the function of a protein.
