A Mutagen is an agent of substance that can bring about a permanent alteration to the physical composition of a DNA gene such that the genetic message is changed. Problem: ________ A base change resulting in a codon specifying the same amino acid ________ Mutation in which a pyrimidine is substituted for a pyrimidine ________ Mutation that causes a mutant phenotype only under restrictive conditions ________ A biochemical mutant that must be supplied with a certain nutrient for growth ________ Mutation that causes death of the zygote Wordbank a) Nonsense mutation b) Silent mutation c) Conditional mutation d) Auxotrophic e) Somatic mutation f) Lethal g) Frameshift h) Transversion i) Transition mutation #geneticMutation #transversionMutation #nonsenseMutation #SilentMutation #ConditionalMutation #Auxotrophic #SomaticMutation #Lethal #Frameshift #Transversion #TransitionMutation
