Dna polymerase occasionally makes errors and adds an incorrect base. a new strand of dna is being produced, and the template strand contains a g. based on your knowledge of the structure of dna, why is it more likely that dna polymerase would accidentally add a t to the new strand instead of a g or an a.

DNA replication occurs in the synthesis phase. And one of the main actors are DNA polymerase which helps make a new copy of a DNA strand. Occasionally, they make errors and pair incorrect bases because of the process and repetition. A is sometimes paired with G is because they are both purines nucleotides and are produced with the same nucleotide components.
