WebAs thymine is irradiated, the C 5 =C 6 bond dissociates and forms a C–C bond with another similarly dissociated C 5 =C 6 bond of an adjacent thymine monomer, forming the thymine dimer. As a result, the C 6 becomes sp 3 hybridized, and the maximum at 3,068 cm −1 is expected to shift below 3,000 cm −1, owing to dimer formation. WebANSWER: Because when 5-methylcytosine is oxidatively deaminated it becomes "thymine", which is a normal DNA base and is not removed by glycosylases. It ultimately leads to transition (C to T) mutations (Me-C:G ® T :G ® T:A & C:G) 8. Explain the principles of error-prone DNA repair.

WebThymine ( / ˈθaɪmɪn /) ( symbol T or Thy) is one of the four nucleobases in the nucleic acid of DNA that are represented by the letters G–C–A–T. The others are adenine, guanine, and cytosine. Thymine is also known as 5-methyluracil, a pyrimidine nucleobase. In RNA, thymine is replaced by the nucleobase uracil.

WebThymine dimer excision repair is initiated by E. coli endonuclease V of bacteriophage T4 that slides on non-target sequences and progressively incises at all dimers within the … WebWhat do dimers do? It happens throughout the cell. For example, dimers form in the cell membrane, where tyrosine-kinase receptors reside, and in the cytosol that contains microtubules composed of tubulin. In the nucleus, hormone receptors, acting as transcription factors, form dimers to increase stability and improve binding to DNA.
