WebbThe photon causes two consecutive bases on one strand to bind together, destroying the normal base-pairing double-strand structure in that area. Pyrimidine dimers are molecular lesions formed from thymine or cytosine bases in DNA via photochemical reactions, [1] [2] commonly associated with direct DNA damage. [3] Webb14 nov. 2024 · Joining two DNA chains with H-bond. Two DNA chains joined together with hydrogen bond. Always adenine (A) joins with thymine (T) and guanine (G) joins with cytosine (C). Here we can see that smaller nitrogen base (T and C) joins with always the bigger one (A and G). This is how it can keep the distance between two chains same in …

Webb12 maj 2024 · An organic molecule that has nitrogen as an element and acts as a foundation in biochemical effects are called nitrogenous bases.. They play important role in the structural organisations of DNA and RNA as both nucleic acids are composed of nitrogenous bases.. The correct answer is :. Option B. Adenine and thymine.. This can … WebbEach nucleotide in DNA contains one of four possible nitrogenous bases: adenine (A), guanine (G) cytosine (C), and thymine (T).
