If a DNA sample were composed of 10 percent thymine what would be the percentage of guanine?
There are four different nucleobases including adenine, thymine, guanine and cytosine. Each nucleobase pairs with it's opposite, for example adenine pairs with thymine and guanine pairs with cytosine. Knowing this, if a DNA sample had 10% thymine that means it would have 10% adenine equalling 20% of the entire sample for the both of them. The remaining 80% of the sample would contain 40% cytosine and 40% guanine.
If thirty five percent thymine what percentages of each of the other bases are contained the same gene?
If 35% of the gene is thymine, then you know that adenine will also be 35%, as they pair together. Similarly, guanine will be 15% and cytosine will be 15% to complement their pairing percentages with adenine and thymine.
If 15 percent of the nucleotides in a DNA molecule guanine what percentage of the nucleotides contain each of the other three bases explain your reasoning?
If 15% of the nucleotides are guanine, then the remaining 85% must be divided among the other three bases: adenine, thymine, and cytosine. Each of these bases will have an equal share of the remaining 85%, so each of them would make up approximately 28.3% of the total nucleotides. This is because DNA is made up of equal amounts of adenine and thymine, and equal amounts of guanine and cytosine, due to the base pairing rule.
If DNA were 40 percent cytosine what would be percent of guanine?
20% because cytosine and guanine have equal amounts. Always
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 a DNA sample were composed of 10 percent thymine what would be the percentage of guanine?
There are four different nucleobases including adenine, thymine, guanine and cytosine. Each nucleobase pairs with it's opposite, for example adenine pairs with thymine and guanine pairs with cytosine. Knowing this, if a DNA sample had 10% thymine that means it would have 10% adenine equalling 20% of the entire sample for the both of them. The remaining 80% of the sample would contain 40% cytosine and 40% guanine.
If the percentage of cytosine in DNA is 17 what is the percentage of adenine?
To clarify, are you talking about on one stand or on both strands? If it is on one strand then it is imposable to tell. there could be up to 83%. (probably not but it is possible) if you are talking 17% on both of the strands then it is implied that it is 17% of guanine This means that there is 66% left. Because on both strands there must be one adenine for every thiamine that means that there is 33% adenine.
If thirty five percent thymine what percentages of each of the other bases are contained the same gene?
If 35% of the gene is thymine, then you know that adenine will also be 35%, as they pair together. Similarly, guanine will be 15% and cytosine will be 15% to complement their pairing percentages with adenine and thymine.
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 15 percent of the nucleotides in a DNA molecule guanine what percentage of the nucleotides contain each of the other three bases explain your reasoning?
If 15% of the nucleotides are guanine, then the remaining 85% must be divided among the other three bases: adenine, thymine, and cytosine. Each of these bases will have an equal share of the remaining 85%, so each of them would make up approximately 28.3% of the total nucleotides. This is because DNA is made up of equal amounts of adenine and thymine, and equal amounts of guanine and cytosine, due to the base pairing rule.
If DNA were 40 percent cytosine what would be percent of guanine?
20% because cytosine and guanine have equal amounts. Always
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%.
A sample of normal double-stranded DNA was found to have a guanine content of 18 percent What is the expected proportion of adenine?
In DNA, the amount of guanine is equal to the amount of cytosine, and the amount of adenine is equal to the amount of thymine. Therefore, if guanine content is 18%, then cytosine content would also be 18%. This means that adenine content would be 32% (100% - 18% - 18% - 32%).
If you have 13 percent thymine in DNA what is then how much adenine do you have?
Then you also have 13% cytosine, 37% guanine, and 37% adenine.
If 15 percent of the nitrogenous base in a sample of DNA is thymine what percentage should be cytosine?
Thymine binds to adenine, so we know that for every thymine, there will be one adenine. That's 15% thymine and 15% adenine. We are left with 70% other nitrogen bases. There are two bases left (guanine and cytosine), both of which bond together in equal numbers. So 70 divided by 2 is 35 -- 35% guanine and 35% cytosine.
Who discovered that the percent of bases in DNA varies from organism to organism?
Erwin Chargaff discovered that the percentage of adenine (A) is equal to thymine (T) and the percentage of guanine (G) is equal to cytosine (C) in DNA. This discovery is known as Chargaff's rules and laid the foundation for understanding the structure of DNA.
What percent of each nitrogen base occurs in human liver cell DNA?
Adenine: 30.3%, Thymine: 29.9%, Guanine: 19.9%, Cytosine: 19.9%.
