protein changes ---> ability changes ---> dna changes ---> gene changes
ability changes ---> dna changes ---> gene changes ---> protein changes
dna changes ---> gene changes ---> ability changes ---> protein changes
dna changes ---> gene changes ---> protein changes ---> ability changes

Explanation:

Genes are segments of DNA. Changes in DNA (like mutations) can lead to changes in genes. Genes code for proteins. Changes in proteins can then lead to changes in an organism's abilities (such as the salamander's ability to regenerate its arm). So the correct sequence is DNA changes → Gene changes → Protein changes → Ability changes.

Answer:

DNA changes ---> Gene changes ---> Protein changes ---> Ability changes
