A double-stranded DNA molecule contains 30 percent guanine (G) What is the percent cytosine (C) in this molecule?

If the DNA macromolecule contains 20% G (guanine), then by Watson-Crick complementarity it must contain 20% C (cytosine). Together this equals 40%, so the percent that is A (adenine) and T (thymine) together is 60%. By Watson-Crick complementarity, then, the percent A in the molecule is half of 60: 30%.


If adenine makes up 30 percent of the bases in a DNA helix what percentage of the bases are cystosine?

There are four bases in the DNA double helix: adenine, guanine, cytosine and thymine. An adenine in one strand always pairs with a thymine in the other strand. Similarly, a cytosine always pairs with a guanine. So the number of adenines always equals the number of thymines, and the number of cytosines always equals the number of thymines. The total number of bases must equal 100%. So if 30% of the bases are adenine, another 30% must be thymine because they always pair with each other. Thymine and adenine added together therefore make 60% of the bases. The remaining 40% must be cytosine plus guanine. If the number of cytosines must equal the number of guanines, the percentage of cytosines must be ....... well, you can work it out for yourself!


If there is 30 of cytosine in a sample of DNA what is the percentage of thymine?

If there is 10% adenine, then there must also be 10% thymine. The remaining 80% of the DNA must be composed of guanine and cytosine, specifically, 40% of each. The answer to your question is therefore 40% cytosine is present in this DNA molecule.


If the DNA analysis of a gene shows 20 adenine bases what would be the percentage of uracil?

as adenine is complementary to thymine,the percentage of thymine is 20% out of 100% 40%is adenine and thymine(20%A +20%T)the rest is 60% cytosine is complementary to guanine so the percentage of cytosine and guanine is 30%and 30%


A double-stranded DNA molecule contains 30 percent guanine What is the percent cytosine in this molecule Where is the promoter region?

30 percent


In a DNA molecule there is 20 percent thymine how much cytosine is in this?

If there is 20% T that means there is also 20% A. 20% + 20% = 40% 100% - 40% = 60% Since there is the same percentage of G and C 60%/2 =30% 30% C 30% G 20% T 20% A This is known as Chargaff's rule.


What if cytosine makes up 22 percent of the nucleotide in a sample of DNA from an organism then adenine would make up what percent of the base?

If yoy have a DNA Double Helix then you know that given the percentage of one base you can find the percentage of the rest. This is because of the fact that the bases always pair with the same partner (A-T and G-C). So whatever percent of ony you have you know its partner will always have the same. You also know that each of the other two bases have an equal share in what is left. So to work through you examlpe. If you know there is 25% A then you also know there is 25% T (as this must be the same). What is left is 50% and because this must be split equally you can see that each of the other bases ( ie. C and G) must also be 25% so in short you have 25% Cytosine. For a different example: If you know you have 30% T then you can see you must also have 30% A. This leaves only 40% so each of C and G must make up 20%.


What is the percent of cytosine in a DNA?

Double Stranded DNA is paired, with Adenine paired with Thymine Cytosine paired with Guanine Then the percent Cytosine in one strand will be exactly the percent Guanine in the other strand. And between the two strands, the percent Cytosine will be equal to the percent Guanine. For a random distribution, the percent should be about 25% for each nucleotide, or 50% for the GC pair, and 50% for the AT pair. However, DNA actually varies considerably from organism to organism. Streptomyces coelicolor A3(2), has a GC content as high as 72% Plasmodium falciparum has a GC content as low as 20%. See Wikipedia link on GC Content.
