Percentage of Guanine in DNA
To determine the percentage of guanine in a DNA molecule, we need to understand the base pairing rules in DNA. In DNA, adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G).
When adenine is 30% in the DNA molecule, we can assume that thymine is also 30% since they always pair together. This is due to the complementary base pairing rule, where the amount of adenine is equal to the amount of thymine in a DNA molecule.
Therefore, to calculate the percentage of guanine, we need to subtract the combined percentage of adenine and thymine from 100%.
Calculation:
1. Since adenine is 30%, thymine would also be 30% as they pair together. So, the combined percentage of adenine and thymine is 30% + 30% = 60%.
2. To find the percentage of guanine, subtract the combined percentage of adenine and thymine from 100%: 100% - 60% = 40%.
Answer:
The percentage of guanine in the DNA molecule is 40%.
Therefore, the correct option is D) 40%.
Summary:
In a DNA molecule, if adenine is 30%, then the percentage of guanine would be 40%. This is due to the complementary base pairing rule, where adenine pairs with thymine and cytosine pairs with guanine. The combined percentage of adenine and thymine is subtracted from 100% to determine the percentage of guanine in the DNA molecule.
