Why is chargaff's rule important to DNA?

Answer 1

Chargaff's rule states that DNA from any cell of any organism has a 1:1 ratio of pyrimidine and purine bases and, more specifically, that the amount of guanine, a purine base, is equal to cytosine, a pyrimidine base; and the amount of adenine, a purine base, is equal to thymine, a pyrimidine base.

So a base pair is composed of a pyrimidine base and a purine base. This pattern is found in both strands of DNA, and is responsible for the base-pairing rule, which states that adenine always pairs with thymine, and guanine always pairs with cytosine..

The nitrogen bases pair with each other by means of hydrogen bonds.

Chargaff's rule helps explain the base-pairing specificity in DNA, ensuring adenine pairs with thymine and guanine pairs with cytosine, maintaining the structural integrity and genetic information during replication.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
