Base substitutions are the simplest type of gene-level mutation, and they involve the swapping of one nucleotide for another during DNA replication. For example, during replication, a thymine nucleotide might be inserted in place of a guanine nucleotide.

Answer:

Base substitutions are the basic form of gene-level alteration, and they occur when one nucleotide is swapped for another during DNA replication. A thymine nucleotide, for example, might be substituted for a guanine nucleotide during replication.
