What is the percentage of cytosine if adenine is 30\%?

Adenine (30\%) = Thymine (30\%) Guanine (20\%) = Cytosine (20\%) Therefore, 60\% A-T and 40\% C-G.

What is the percentage of thymine if adenine is 30\%?

Correct answer: Together, adenine and thymine compose 70\% of the segment. This means that 30\% of the section is composed of guanine-cytosine pairs. Since these two bases will be equal in quantity, 15\% of the DNA section will be cytosine bases.

What is the percentage of cytosine if 20\% of nitrogenous bases in a DNA molecule is adenine?

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\%.

What is the ratio of guanine to cytosine in a double stranded DNA molecule?

In DNA, guanine is 10\%. If guanine=10\% as guanine will always pair with cytosine, i.e.cytosine is also 10\% then adenine and thymine accounts 80\% as adenine will always pair with thymine.

What is Chargaffs law?

Chargaff rule: The rule that in DNA there is always equality in quantity between the bases A and T and between the bases G and C. (A is adenine, T is thymine, G is guanine, and C is cytosine.) Also known as Chargaff’s ratios.

What percentage of the molecule is cytosine?

18\%
In a DNA molecule cytosine is 18\%.

What is the ratio of adenine to cytosine in dsDNA?

According to Chargaff’s rule, In dsDNA the number of adenine molecules is equal to thymine molecules and the number of guanine molecules is equal to cytosine molecules. Means it has equal ratio of pyrimidine (cytosine and thymine) and purine (adenine and guanine). Given that, C=20\%. => G=20\%. Thus, G+C=40\%.

What is the percentage of adenine and thymine in DNA?

Let`s get to the point! You have 20\% of adenine. 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\%.

What is the percentage of cytocine and guanine with thymine?

The amount of Guanine will always equal the amount of Cytocine. So, if Adenine equals 23\% of your sample and Adenine equals Thymine, then Thymine equals 23\%. That gives you the percentage of Cytocine and Guanine together. Since I’m going to tell you how to find the answer yourself so you can figure out other problems like it.

What is the percentage of G + C content in dsDNA?

It means that the number of adenine molecules is equal to thymine molecules and the number of guanine molecules is equal to cytosine molecules. \% A = \% T and \% G = \% C If dsDNA has 20\% of cytosine, then according to the law, it would have 20\% of guanine. Thus, percentage of G + C content = 40\%
