UV-induced DNA damages, such as the thymine dimer or 6鈥 4 photoproduct, are efficiently repaired by the nucleotide excision repair (NER) mechanism. The defects in NER cause xeroderma pigmentosum (XP) group A to
What type of bonds is holding DNA together? What are 3 parts of a DNA molecule? A photon of ultraviolet light hits double-stranded DNA and creates a covalent cross-link between adjacent thymines in the same strand (a thymine dimer). What is likely to happen? a. The DNA strand...
When the normal conformational chemistry of DNA is lost due to any of these internal or external factors, we can say that there is a lesion in the DNA. As in the image, the normal conformational symmetry of DNA is lost due to formation of thymine dimer by UV Light and this created a ...

Describe or explain how the presence of a thymine dimer in DNA being used as the template strand during DNA replication can lead to a frameshift mutation. What is the function of the araC gene in the pGLO plasmid? How do purines and pyrimidines affect DNA structu...
