Informatif Posting on DNA Molecule Ratio

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?

A) 1 million

B) 2 million

C) 3 million

D) 4 million

Answer:

The correct answer to the question above is:

A) 1 million

When dealing with the ratio of adenine (A) molecule to thymine (T) in a DNA molecule which is 1:1, it means that for every one molecule of adenine, there is an equal amount of thymine molecule in the DNA strand.

Therefore, if there are 1 million adenine (A) molecules in the DNA strand, the number of thymine (T) molecules is also expected to be 1 million. This is because of the 1:1 ratio relationship between A and T molecules, indicating an equal quantitative presence of both in the DNA strand.
