Chargaff's rule states that A (adenine) only bonds with T (thymine) and C (cytosine) only bonds with G (guanine) in a DNA strand. Since DNA replication is semi-conservative, this complementary base pairing allows two of the DNA molecules to be identical to each other as they have the same base sequence. The new strands made are complementary to their template strands and also identical to the other template. Complementary base pairing is important in the conservation of the base sequence of DNA because adenine always pairs with thymine, while guanine pairs up with cytosine. All in all, complementary base pairing has a huge role in the conservation of the base sequence of DNA.
so basically if you have a fish in a bag in a hot tank and we cant feel it its because some things need to actually get hot enough or cold enough forus to feel the tempeture so basically animals have better feeling for the heat or the cold than humans
