Question

if a segment of one side of a dna molecule has 500 adenine bases, how many thymine bases does the other side have? 0 125 250 500

Explanation:

Step1: Recall base - pairing rules in DNA

In DNA, adenine (A) pairs with thymine (T) through hydrogen bonds. So, the number of adenine bases is equal to the number of thymine bases in a DNA molecule.

Step2: Apply the rule to the given problem

If one side of the DNA segment has 500 adenine bases, then the other side (complementary strand) must have 500 thymine bases to pair with them.

Answer:

500
