WebApr 28, 2024 · Substitution mutations are situations where a single nucleotide is changed into another. In organisms having double-stranded DNA or RNA, this usually means that the corresponding base pair is also altered. For example, an A:T base pair could be mutated into a G:C base pair or even a T:A base pair. WebThe term duplication was coined by Bridges in 1919, and the first duplications were described in Drosophila melanogaster. ADVERTISEMENTS: Duplications may originate in the following four ways: 1. Primary structural change of chromosomes 2. Disturbances in the crossing over process (unequal crossing over) ADVERTISEMENTS: 3.
