WebMutagens have different mutational specificity Base analogs (they incorporate into DNA) similar to nitrogenous bases of DNA, but have altered pairing properties e.g., 5-bromouracil (5-BU) and 2-aminopurine (2-AP) result in transitions can change a thyamine to a cytoseine What are intercalating agents? Intercalating agents are a type of mutagen WebTypes Of Mutagens. Chemical mutagens are classified as alkylating agents, cross-linking agents, and polycyclic aromatic hydrocarbons (PAHs). Alkylating agents act by adding molecular components to DNA bases, which alters the protein product. Cross-linking agents create covalent bonds with DNA bases, while PAHs are metabolized by the human body ...
WebBiological mutagens: Viruses are the common mutagens that transfers their genetic material and disrupts our DNA function and synthesize viral protein instead. Bacteria are also responsible in breaking and blocking DNA replication processes. Transposon is a section of non-coding DNA sequences that disrupts the DNA function by altering gene … WebMutagens. Chemical agents that increase the rate of genetic mutation by interfering with the function of nucleic acids. A clastogen is a specific mutagen that causes breaks in chromosomes.
