Question

When DNA is copied, sometimes a new, incorrect, base pairing appears within the structure of a new DNA molecule replacing original base pairs. This mistake is called a base-pair

Answer 1

Well it substitutes one base for another, so "substitution" is probably the word you're looking for. Actually the better term for the resulting gene is a "single nucleotide polymorphism" or SNP.
