Mutations caused by chemical and physical mutagens are classified based on how they alter the DNA sequence. The two major types of base substitution mutations are transitions and transversions. A third category, frameshift mutations, involves insertion or deletion of bases…
Chemical mutagens are agents that alter our genetic code. Most of them work by directly attacking and damaging existing DNA. However, Base Analogue Mutagens act like molecular imposters. Because they look almost exactly like normal DNA building blocks, they trick…
A chemical mutagen is any chemical substance that increases the frequency of mutations above the spontaneous background rate. Chemical mutagens act by damaging DNA in different ways — some mimic normal bases, some chemically modify existing bases, some physically insert…
