What type of mutagen is acridine?
frameshift mutagens
This observation plus the ability of acridine-induced mutations to prevent production of functional proteins led Sidney Brenner et al. to propose that acridine-induced mutations are caused by the deletion or addition of a base pair as shown in Figure 3. Thus, acridines are frameshift mutagens.
Is acridine a mutagen?
For example, acridine dyes are mutagenic. An important finding was that while acridine-induced mutations revert spontaneously or by exposure to acridines, they are not reverted by mutagens known to induce base substitution mutations.
