Question

In a DNA molecule the ratio of adenine (A) molecule to thymine (T) is 1:1. If in a strand of DNA there are 1 million A molecules, how many T molecules are expected in the same strand?

Answer 1

Since it is a 1:1 ratio, they must be equal so T must also have 1 million molecules

Answer 2

Answer: I million.

Step-by-step explanation:

The DNA molecule is made of nitrogenous bases, phosphate group and pentose sugar.

The nitrogenous bases in the DNA molecule combines complementary to each other.

The adenine combines with the thymine and the guanine combined with cytosine. This means that they are found in equal amount in the DNA strand.

So, If there is 1 million adenine molecule then there will be 1 million thymine in the DNA strand.
