WebA slippage event normally occurs when a sequence of repetitive nucleotides ( tandem repeats) are found at the site of replication. Tandem repeats are unstable regions of the genome where frequent insertions and deletions of nucleotides can take place, resulting in genome rearrangements. [3] WebThe mechanism of the smallest single base insertion mutations is believed to be through base-pair separation between the template and primer strands followed by non-neighbor base stacking, which can occur locally within the DNA polymerase active site.

WebIn the ladder model of DNA, the base-pair rule says that adenine (A) always pairs with thymine (T) and cytosine (C) always pairs with guanine (G). This happens because hydrogen bonds form between the nitrogen atoms of the two bases. To find the complementary strand, you just swap out each nitrogen base for its partner that is the opposite of it. WebBase Pairing.
