In researching the structure of DNA Erwin Chargaff found the amount of adenine always equaled the amount of which other base?
thymine
In researching the structure of DNA Erwin chargaff found the amount of adenine always equals the amount of which other base?
thymine
In researching the structure of DNa erwin chargaff found the amount of adenine always equal the amount of which other base?
thymine
In researching the structure of DNA Erwin Char gaff found the amount of adenine always equaled the amount of which other base?
Thymine. Discovered in the late 1940s, this is known as "The Chargaff's Rules": DNA has equal numbers of adenine and thymine residues (A = T) and an equal number of guanine and cytosine (G = C). This was one of the most important features for Watson and Crick to solve the structure of DNA molecule in 1953.
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.
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).
In researching the structure of DNA Erwin Chargaff found the amount of adenine always equaled the amount of which other base?
thymine
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.
Who discovered the amount of adenine in DNA is always equal the amount of thymine?
Erwin Chargaff
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.

What do Chargaff's rules state about adenine and thymine?
In each species, the amount of adenine equals the amount of thymine.
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.
How did the double helix structure match Chargaff's observations?
Chargaff observed that the number of Guanine units in a section/piece of DNA was the same as the number of Cysteine units and that the number of Thymine units equaled the number of Adenine units. This matched the double helix structure because Cysteine pairs with Guanine, and Thymine pairs with Adenine - meaning that Chargaff was right in that there must be an equal number of Cysteines and Guanines as well as equal Thymines and Adenines.
