# Is 15% of a DNA sample is made up of thymine what percentage of the sample is made up of cytosine?

## Is 15% of a DNA sample is made up of thymine what percentage of the sample is made up of cytosine?

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.

## How much cytosine is present in DNA if there is 15% of adenine?

According to Chargaffs rule, the total amount of adenine released is equal to the total amount of thymine and the total amount of cytosine is equal to the total amount of guanine, ie, A=T and C=G. Thus, if DNA molecule contains 15% adenine then C and G will constitute 70%, out of which guanine will be 35%.

## Is DNA sample were composed of 10% thymine what would be the percentage of guanine?

The correct answer is 40%. In DNA, adenine (A) always bonds with thymine (T), while guanine (G) always bonds with cytosine (C). So, the percentages of A and T will be equal, while the percentages of G and C would also be equal. In this sample, there exist 10% of guanine, therefore there's also 10% of cytosine.

## What percentage is thymine and adenine?

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

## What amount of thymine T would be found in A strand of DNA composed of 15 %?

In a strand of DNA composed of 15% cytosine, what amount of thymine would be found in this DNA? There would be 70% adenine and thymine in the DNA. This would mean that there is 35% thymine.

## What amount of thymine would be found in a strand of DNA composed of 15 cytosine?

In a strand of DNA composed of 15% cytosine, what amount of thymine would be found in this DNA? There would be 70% adenine and thymine in the DNA. This would mean that there is 35% thymine.

## How do you calculate guanine percentage?

## What would be the percentage of thymine in a double-stranded DNA sample which contains 20% cytosine of the total bases a 10% B 20% C 30% D 40%?

Therefore, Guanine would be 20% and total of G+C = 40% and hence A+T would be 60% that is 30% each. Hence, option C is correct answer.

## What amount of thymine T would be found in a strand of DNA composed of 15 %?

In a strand of DNA composed of 15% cytosine, what amount of thymine would be found in this DNA? There would be 70% adenine and thymine in the DNA. This would mean that there is 35% thymine.

## Is the percentage of thymine in DNA is 20% what will be the percentage of guanine in DNA?

So, the correct answer is '30%'.

## What will be the percentage of guanine in a DNA molecule having 20% adenine?

What will be the percentage of guanine in a DNA molecule having 20% adenine ? In a DNA molecule, the adenine is `15%` ….

## How do you calculate adenine percentage?

If you need to calculate the percentage of adenine in a DNA sample, you can use Chargaff's rule to solve the problem. For example, if you know the DNA sample is 20 percent thymine, you automatically know it is 20 percent adenine, as well, since they pair together.

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

Hence, the sum of the purine residues equals the sum of the pyrimidine residues; i.e. A + G = T + C. Here, (A) = 30%, therefore, % of (T) is also 30%. Thus, (G)+(C) = 100 – 60 = 40%. (G) = 20% and (C) = 20%.

## What is the percentage of adenine if thymine is 20%?

So, the correct answer is '30%'.

## What is the percentage of guanine in a DNA sample containing 20% thymine?

Answer and Explanation: A double-stranded DNA molecule with 20% thymine would contain 30% guanine.

## What is the percentage of adenine if a DNA has 20% cytosine?

30% Thus, if a double-stranded DNA has 20% cytosine, it has 20% guanine. Thus, C + G makes 40% of the total bases. The remaining 60% includes both adenine and thymine which are in equal amounts. So, the percentage of adenine is 30%.

## What is the percentage of cytosine in the DNA having 18% of adenine?

Now, total percentage of total A and T = 100 – 18 – 18 = 64, so the percentage of A is 64/2 = 32%.

## What percentage is thymine?

In a typical DNA molecule, the proportion of thymine is 30% of the N bases.

## How much adenine guanine and cytosine are present if a DNA strand contains 20% thymine?

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%. Then divide this by 2 and you will get 30%.

## Is adenine makes 30% of the DNA molecule what will be the percentage of thymine guanine and cytosine in it?

Thymine −30%, Guanine −20%, Cytosine −20% (Chargaffs nitrogen base pairing rule which states that amount of Adenine is equal to Thymine and Guanine is equal to Cytosine.

## What is percentage of thymine in DNA?

In a DNA, the percentage of thymine is 20 %, then what is the percentage of guanine?

## What is the percentage of adenine present in A gamete when guanine is 20% in root cells of the same plant?

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 percentage is cytosine in DNA?

18% In a DNA molecule cytosine is 18%.

## What is the percentage of guanine if the thymine is 20%?

So, the correct answer is '30%'.
