WebHow and why do base analogs lead to mutations? Describe and Explain why loss-of function mutations are frequently recessive, gain-of-function mutations are frequently dominant 4. Difference between a transition and a transversion mutation? 7. Three major types of RNAs are mRNA, rRNA, and tRNA. WebDec 30, 2024 · These base analogs induce mutations because they often have different base-pairing rules than the bases they replace. Other chemical mutagens can modify normal DNA bases, resulting in different base-pairing rules. For example, nitrous acid deaminates cytosine, converting it to uracil.
