WebOct 17, 2024 · UVB light causes thymine base pairs next to each other in genetic sequences to bond together into pyrimidine dimers, a disruption in the strand, which … WebWhy is a thymine dimer harmful? The more you expose your skin to UV light, the more likely you are to get the very unlucky combination of thymine dimers in a cell that are not repaired and lead to cancer in that cell. It can tens of years for such a cell to grow and divide into a cancer tumor you can see, but once it does, it becomes deadly.

Where does the pyrimidine dimer come from in DNA? WebUV radiation can make cytosine and thymine bases react with neighboring bases that are also Cs or Ts, forming bonds that distort the double helix and cause errors in DNA … perkins tire scotts mi
