What is the percentage of guanine in a DNA sample containing 10\% thymine?

In this sample, there exist 10\% of guanine, therefore there’s also 10\% of cytosine. Therefore, thymine and adenine would make up a total of 100\%−10\%−10\%=80\% of the DNA .

What is the percentage of thymine to guanine?

Since cytosine and guanine are present in equal amounts, we can simply divide their sum by 2. The final composition is 22\% adenine, 22\% thymine, 28\% cytosine, and 28\% guanine.

What percent of DNA is thymine?

In a DNA sample, the percentage of adenine is 40\% and percentage of thymine is 60\%.

What is the ratio of adenine to thymine?

Chargaff’s rules state that DNA from any species of any organism should have a 1:1 stoichiometric ratio of purine and pyrimidine bases (i.e., A+G=T+C) and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine.

What is the percentage of guanine in a DNA sample containing 30\% thymine?

Therefore if there is 30\% thymine in DNA then 30\% adenine would be present in the DNA which makes a total of 60\%. The rest 40\% is made by cytosine and guanine. So cytosine will make 20\% and guanine will make 20\% of nucleotide in the DNA. Therefore the correct answer is 20\%.

What percentage of the DNA is thymine?

3. In a DNA sample, the percentage of adenine is 40\% and percentage of thymine is 60\%.

What percentage of nucleotides will be thymine?

8\% will be thymine.

What is the percentage of thymine in this DNA sample?

In this sample, there exist 10\% of guanine, therefore there’s also 10\% of cytosine. Therefore, thymine and adenine would make up a total of 100\% −10\% − 10\% = 80\% of the DNA. As they must exist in equal amounts, the percentage of thymine in this DNA sample will be 80\% ÷ 2 = 40\%.

What is the percentage of adenine and guanine in DNA?

You might already know that, adenine and guanine are the purines and thymine and cytosine are the pyrimidines in the DNA. Using Chargaff’s rules, if thymine content is 10\% of the DNA, then adenine should also be 10\% and the guanine and cytosine make up the rest 80\% of DNA comprising of 40\% guanine and 40\% cytosine.

What should be the GC content of my DNA sample?

Using Chargaff’s rules, if thymine content is 10\% of the DNA, then adenine should also be 10\% and the guanine and cytosine make up the rest 80\% of DNA comprising of 40\% guanine and 40\% cytosine. That means the GC content of your DNA sample is 80\% which is normal for some species of micro-organisms.

What is the percentage of adenine in your hair?

That means that Adenine also has to be 10\% because where there is a T on one strand there will be an A on the complementary strand. Now you have accounted for 20\% of the total. There are only two more options for the remaining 80\% – Cytosine and Guanine.
