Which term describes when DNA is lost, rearranged or paired in error?

• A. Mutation
• B. Trait
• C. Congenital
• D. Genetic

Answer: (A)

Mutations are changes to the DNA sequence, including when DNA is lost (deletion), rearranged (inversions, translocations, duplications), or paired incorrectly during replication. These alterations can change genes and affect how organisms function, and they’re the term that covers errors in the genetic material itself. A trait is simply an observable characteristic, not the process of DNA change. Congenital refers to conditions present at birth, not the mechanism that alters DNA. Genetic describes something related to genes in general, not specifically the occurrence of DNA errors.
