Answer 1
Answer:

In the DNA of living things, Chargaff found that the ratios of guanine and cytosine were comparable to those of thymine and adenine. So, the correct option is B.

What is Chargaff's rule?

Chargaff's rule was discovered by Austrian biochemist Erwin Chargaff, states that in DNA, the amount of adenine (A) is equal to the amount of thymine (T) and the amount of guanine (G) is equal to the amount of cytosine (C).

This means that A always pairs with T, and G always pairs with C, forming the base pairs which make up the "rungs" of the DNA double helix. This discovery was a crucial piece of information in determining the structure of DNA and helped Watson and Crick to develop their model of the double helix.

Therefore, in the DNA of living things, Chargaff found that the ratios of guanine and cytosine were comparable to those of thymine and adenine. So, the correct option is B.
