According to chargaffs rules blank the amount of always equal the amount of thymine?
Adenine
What was Chargaff's conclusion?
Chargaff made an observation about DNA that was very important in the determination of its structure. He noticed that the amount of adenine always equaled the amount of the thymine, and the amount of cytosine always equaled the amount of guanine. This principle is known as chargaffs rule, and it helped Watson and crick eventually realize that A paired with T and C paired with G.
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.
Nitrogen Bases in DNA?
Macromolecules In addition to the C, the H and the O, they also contain nitrogen (N). All of these elements are arranged to form amino acids. Amino acids are the building blocks ... But, you notice that you have two types of nucleic acids. ... These nitrogenous bases pair up to help form the famous double helix you may have heard about with DNA.
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!
According to chargaffs rules blank the amount of always equal the amount of thymine?
Adenine
Why is the amount of guanine always equal to the amount of cytosine?
Amount of guanine is always equal to cytosine
The amount of guanine always equals the amout of what?
The pyrimidine cytosine (C) always pairs with the purine guanine (G) so there must always be equal amount of both in DNA.

What statement about Chargaffs rules is carrect?
Observations by Erwin Chargaff that concentrations of the four nucleotide bases differ among species. Within a species, the concentrations of adenine and thymine are always about the same and the concentrations of cytosine and guanine are always about the same. In each species, the amount of adenine equals the amount of thymine. The amount of guanine equals the amount of cytosine.
What is cytosines?
Cytosine is a nitrogen bases that is found in the DNA. There is four nitrogen bases and this is one of them. The amount of cytosine in cells always equals the amount of guanine, and the amount of adenine always equals the amount of thymine.
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.
If a DNA molecule is found to be composed of 40 thymine what is the percentage guanine would be expected?
Since G Pairs with C, and A pairs with T....%G=%C, therefore the bases are also 40% Cytosine Final result of all bases would be: 40% Guanine 40% Cytosine 10% Adenine 10% Thymine
How many Guanine's are in a DNA?
There is no consistent amount of guanine in everyone's DNA, but there is an equal amount of guanine and cytosine as well equal amounts of thymine and adenine.
Chargaff's observations included that in every RNA molecule that adenine always equaled the amount of cytosine?
Chargaff's data showed that for each organism he studied the amount of adenine always equaled the amount of thymine (A=T) likewise, the amount of guanine always equaled the amount of cytosine (G=C).

Who stated that thymine and adenine always pair up?
Erwin Chargaff. "In 1949, Erwin Chargaff, a biochemist working at Columbia University, in New York City, made an interesting observation about DNA. Chargaff's data showed that for each organism he studied, the amount of adenine always equaled the amount of thymine (A=T). Likewise, the amount of guanine always equaled the amount of cytosine (C=G). However, the amount of adenine and thymine and of guanine and cytosine varied between different organisms." -From my biology textbook, "Biology: Principles & Explorations," Holt, Rinehart, and Winston.
