WebÄ Base alteration mutants modify a base causing specific mispairing of bases; Mechanism of base alteration using alkylating agents such as EMS and NG to generate transition mutations (14-9); Intercalating agents such as proflavin, acridine orange and ICR compounds mimic bases and cause single nucleotide insertion and deletion mutations … WebSolution: Base analogs have structures similar to the nucleotides and can be incorporated into the DNA in the course of replication. Many analogs tend to mispair, which can lead to mutations. DNA replication is required for the base-analog- induced mutations to be incorporated into the DNA.
WebAug 24, 2024 · Some of the base analogues are highly specific mutagens, e.g. N4- hydroxycytidine , which induces almost exclusively AT—-GC base-pair transitions, whereas … WebBase analogs are derivatives of the normal DNA bases, which may mimic to varying extents the properties of the normal bases. As such, they have the ability to interfere with normal nucleotide metabolism and exert a variety of toxic and mutagenic effects. One example of their application as a toxic compound is usage as antiviral or antitumor agents.
WebJul 19, 2024 · The base-pairing rules are based on the hydrogen-bonding capacity of nucleotides with their bases in the keto tautomer. A nucleotide whose base is in the enol tautomer can pair with the "wrong" base in another nucleotide. For example, a T in the rare enol isomer will pair with a keto G (Figure 7.1. 2 ), and an enol G will pair with a keto T.
