Copyrights By Li Creative Technologies - 2022, If The Thymine (T) Content Of Dna Is 29%, What Is The Content Of Guanine (G)? The amount of guanine is 28%. Three parts make up a nucleotide: A Nitrogenous base either adenine, thymine, guanine, or cytosine. Step by step video solution for [object Object] by Biology experts to help you in doubts & scoring excellent marks in Class 11 exams. The content of adenine is, Difference between Plant cell and Animal cell (15 Differences) | Plant Cell vs Animal Cell, Difference between Mitosis and Meiosis (32 Differences), Difference between Reducing and Non-reducing sugars. From 100 remains 60% which is divided equally between guanine and cytosine, so each is 30%. Right on! Chargaffs Experiment and Why is Chargaff's Rule Important? In this sample, there exist 10% of guanine, therefore theres also 10% of cytosine. What were the percentages of thymine and guanine in this sample of DNA? Now as per the given question, the percentage of Adenine is 30. 1 Answer Rawda Eada Dec 30, 2015 Since adenine is 20%, then thymine is 20% as well. WebAccording to the rule given by Chargaff, A + G = C + T. Adenine (A) will always pair with Thymine (T). It does not store any personal data. guanine is 10%. Guanine always pairs with Cytosine. No worries! In this sample, there exist 10% of guanine, therefore theres also 10% of cytosine. therefore if [A]=40% then the [T] will also be 40%. The correct answer is B. $60\% $ gets equally divided between Cytosine and Guanine.i.e. Scientists have not always known the function of DNA. If the ratio (A+G)/(T+C) in one strand of DNA is 0.7, what is the same ratio in Chargaff's rule means that in any sample, the concentration of adenine will always equal the concentration of its pair thymine, and the concentrations of guanine and cytosine will be equal, too. From 100% DNA bases subtract 40% and you will get 60%. This means that A = T. Cytosine (C) will always pair with Guanine (G). The possibility of Adenine=40% and Thymine=60% is only in single stranded DNA molecule. The rest 40% is made by cytosine and guanine. Thanks. How does Charle's law relate to breathing? Try BYJUS free classes today! Answer link 15% 30% 35%. As a result of the EUs General Data Protection Regulation (GDPR). If Adenine makes 30% of the DNA molecule, what will be the percentage of Thymine, Guanine and Cytosine in it? c. What percentage are guanine? You also have the option to opt-out of these cookies. In the question, the DNA sample referred is a single stranded DNA. These four bases are adenine, guanine, thymine and cytosine. Enter your email address to receive updates about the latest advances in genomics research. Since there needs to be an equal number of guanine and cytosine bases, we simply divide 60 by two to get 30 bases for each.
