Question

1. chargaffs rule states that the dna of any species contains equal amounts of _ and _ and also equal amounts of _ and _. 10. based on this information, scientist could predict that the base _ pairs with _ and the base _ pairs with _ in the formation of the dna molecule.

Explanation:

Chargaff's rule is a fundamental concept in molecular biology. It states that in DNA, the amount of adenine (A) is equal to thymine (T), and the amount of guanine (G) is equal to cytosine (C). This is because of the base - pairing rules in DNA. Adenine pairs with thymine through two hydrogen bonds, and guanine pairs with cytosine through three hydrogen bonds.

Answer:

1. adenine; thymine; guanine; cytosine
2. adenine; thymine; guanine; cytosine
