Answer: A change in the sequence of DNA bases--> Joining amino acids in sequence --> Appearance of characteristics
Explanation:
A mutation is a permanent shift or change from the normal DNA sequence that makes up a gene and affect traits which makes the sequence becomes different from what is commonly found in people. Mutations vary from distortion of a single DNA building block to a large segment of a chromosome.
