WebJan 27, 2024 · The most common pyrimidine dimer is the cis-syn-cyclobutane pyrimidine dimer (CPD) lesion between adjacent thymines. If not repaired the CPD lesion is highly … A cyclobutane pyrimidine dimer (CPD) contains a four membered ring arising from the coupling of the two double-bonded carbons of each of the pyrimidines. Such dimers interfere with base pairing during DNA replication, leading to mutations. A 6–4 photoproduct (6–4 pyrimidine–pyrimidone or 6–4 … See more Pyrimidine dimers are molecular lesions formed from thymine or cytosine bases in DNA via photochemical reactions, commonly associated with direct DNA damage. Ultraviolet light (UV; particularly UVB) … See more Due to the excellent photochemical properties of DNA, this nature-made molecule is damaged by only a tiny fraction of the … See more Pyrimidine dimers introduce local conformational changes in the DNA structure, which allow recognition of the lesion by repair enzymes. In most organisms (excluding placental mammals such as humans) they can be repaired by photoreactivation. … See more • DNA repair See more Translesion polymerases frequently introduce mutations at pyrimidine dimers, both in prokaryotes (SOS mutagenesis) and in eukaryotes.
