Detailed explanation-1: -Since adenine is 20%, then thymine is 20% as well. The total of both is 40%. From 100 remains 60% which is divided equally between guanine and cytosine, so each is 30%. Uracil is not found in DNA but it will have the same percentage as thymine, i.e the RNA will have 30% uracil.
Detailed explanation-2: -If you have 20% of adenine than you have 20% of thymine, because the amount of adenine and thymine is equal. 20% plus 20% is 40% of adennine and thymine. From 100% DNA bases subtract 40% and you will get 60%.
Detailed explanation-3: -Answer and Explanation: A double-stranded DNA molecule with 20% thymine would contain 30% guanine.
Detailed explanation-4: -Updated On: 27-06-2022 Thus, If a double stranded DNA has 20% of cytosine, it has 20% of guanine. Thus, cytosine plus guanine make 40% of the total bases. The remaining 60% includes both adenine and thymine which are in equal amounts. Therefore, the percent of adenine is 30%.
Detailed explanation-5: -The remaining 60% represents both G + C molecule. Since cytosine and guanine are always present in equal numbers, the percentage of guanine molecule is 30%.
