Watson and Crickâ??s model explains that hydrogen bonds can only form between certain base pairs. Thymine can only bond with adenine and guanine can only bond with cytosine. This is why there are equal amounts of thymine and adenine in DNA.

Because adenine binds only to thymine and thymine binds only to adenine. Similarly for guanine and cytosine to each other. This means that there has to be equal amounts because they always are paired together in DNA.

Yes, it did.

Though the two did not know for sure, they did believe that the amounts were very close to each other.

Yes because they always paired thymine with adenine or always paired adenine with thymine, never pairing either with cytosine or guanine. Therefore they are in equal amounts.

Since the subject of multiple-based compounds was found in this new system of the model, the DNA in the real model had too much thymine and coryph in it to be a real adenine molecule.

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!


What is the amount of matter contained in an object?

Its mass.By weight, the amount of matter an object contains is its mass.By size, the amount of matter an object contains is its volume.


Which biological molecule contains a large amount of the element nitrogen?

Proteins


Why making measurements is important to scientist?

this is important because the measurements help scienstst to observe the right amount of a substance they are adding to another this also give scientist the approximate measurements of volume


What is a solution that contains a large amount of solute?

The solution has a lower concentration. We can also say that it is dilute. Concentration is the amount of solute over the volume of solvent, thus when a large amount of solvent is used, concentration of the solution is low.

The amount of adenine will always equal what?

adenine In a DNA strand, the amount of Adenine equals the amount of Thymine, and the amount of Guanine equals the amount of Cytosine. So Adenine is your answer.


What do Chargaff's rules state about adenine and thymine?

In each species, the amount of adenine equals the amount of thymine.


Who discovered that the amount of adenine in DNA always equals the amount of thymine?

Those are Chargraff's Rules. You're wrong to think that adenine and thymine are the only pairs however because in RNA, adenine always pairs with uracil. Thymine is not in RNA. Adenine and Guanine are purines. Cytosine, thymine, and uracil are purimidines. Sources: My Science class and textbook Hope this helped!


Do cells contain the same amount of T as A?

In terms of DNA base pairing, adenine and thymine are complimentary bases. Therefore, for every base of adenine, there will be a base of thymine to compliment it. Therefore, cells contain the same amount of the bases adenine (A) and thymine (T).


What is correct about Chargaff's rule for each species A adenine equals guanine B adenine equals thymine C adenine equals cytosine D adenine guanine thymine and cytosine amounts are equal?

in each species the amount of adenine equals the amount of cytosine


A sample of DNA contains 500 adenine bases how many thymine bases does it contain?

It depends on the organism. Different organisms have different relative amounts of nitrogenous bases. The only thing we can say for sure is that the amount of thymine in a given organism's genome will be just about the same as the amount of adenine.


In DNA adenine pairs with?

Short answer: Adenine More information: In the model of DNA that was discovered by Rosalind Franklin, James Watson and Francis Crick in 1953 proposed that DNA was a double helix structure with 4 bases which pair to each other. Due to experiments that had been carried out by other scientists at the time (namely Erwin Chargoff in 1949) he showed that despite the amount of DNA present the amount of adenine was always equal to the amount of thymine and the amount of cytosine to the amount of guanine. When Watson had this information he suddenly realised that the adenine-thymine bond was the same length as the cytosine-guanine bond and therefore they would pair to each other in a double helix model. Thymine and adenine are held together by a double hydrogen bond; whereas cytosine and guanine form a triple hydrogen bond.


According to chargaffs rules blank the amount of always equal the amount of thymine?

Adenine


In each species does the amount of adenine equal to the amount of thymine?

Every adenine in DNA will be paired to a thymine. However in RNA adenine is paired to uracil. So no - all else being equal since there is DNA and RNA in a body there will not be equal amounts.


If you performed a laboratory analysis of DNA you would find that the amount of adenine is the amount of thymine.?

Yes, because Adenine always pairs with Thymine so every time you have a Thymine their will be always a Adenine to pair with it. (If your confused just think about the stand of DNA then read what a said again)


WHICH WAS A CONCLUSION OF GRIFFITH'S WORK WITH STREPTOCOCCUS PNEUMONIA?
