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

1 million adenine molecules

Answer 2

As it is said in DNA molecule the ratio of the adenine (A) molecule to thymine (T) is 1:1, which means the count of both the molecules (A and T) are same.

If in a strand the A molecules are found in 1 million, T molecules will be of the same quantity, which is 1 million, which makes the ratio 1:1.
