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. WebWhen cleansing is inefficient, base-analogs are incorporated into DNA. Damaged bases lead to mutations in replication cycles or can be correctly repaired by base excision repair. Intermediates of this repair can lead to mutagenesis, DNA breaks, and chromosome changes.

WebHow do base analogs lead to mutations? 1) Baseanalogs have structural similarities with the original nucleotide bases.Therefore, they may get incorporated into the DNA in the course of replication.Many of the analogs tend to mispair which may lead to mutations. WebThese rarer misincorporations lead to transversions. Question 7.1. If a dCTP is incorporated into a growing DNA strand opposite an A in the ... certain nucleoside and base analogs adopt these alternative isomers more readily. For instance 5-bromo-deoxyuridine (or 5-BrdU) is ... Many mutations do not result from errors in replication. Chemical ... under the cabinet water key

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. WebExpert Answer. 100% (1 rating) Base analogues Base analogues are chemical compounds that are so close to the usual nitrogen bases of DNA that they are occasionally inserted … WebHow do base analogs lead to mutations? Base analogs have structures similar to the nucleotides and if present, may be incorporated into the DNA during replication. Many analogs have an increased tendency for mispairing, which can lead to mutations. DNA replication is required for the base analog-induced mutations to be incorporated into the … under the cajun moon mindy starns clark
