Erwin Chargaff found the amount of adenine always equaled the amount of which other base?
Erwin Chargaff discovered that the amount of adenine in DNA always equaled the amount of thymine. This observation is part of his rules, which state that in double-stranded DNA, the amount of guanine equals that of cytosine as well, highlighting the base pairing relationships crucial for the structure of DNA.
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.
Whose research indicated that the bases in DNA must mach with each other in some regular pattern?
Erwin Chargaff's research in the 1940s revealed that the amount of adenine in DNA always equaled the amount of thymine, and the amount of guanine equaled the amount of cytosine. This finding indicated that the bases in DNA must pair up in a specific and consistent manner.
What led to the understanding of complimentary base - pairings in DNA?
The understanding of complementary base pairing in DNA was significantly advanced by the work of James Watson and Francis Crick, who proposed the double helix model of DNA in 1953. They built upon Chargaff's rules, which showed that the amounts of adenine (A) always equaled thymine (T) and cytosine (C) always equaled guanine (G) in DNA. This led to the conclusion that A pairs with T and C pairs with G, facilitating the accurate replication of genetic information. Subsequent research further confirmed the significance of these pairings in maintaining the structure and function of DNA.
How much is 87000 tons?
87,000 tons is equaled to 174,000,000 pounds
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).

How did 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.
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.

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.

Describe the data used by Watson and crick to determine the structure of DNA?
Watson and Crick used X-ray crystallography data produced by Rosalind Franklin and Maurice Wilkins, which revealed the helical structure of DNA. They also drew inspiration from Chargaff's data on the base composition of DNA, showing that adenine equaled thymine and cytosine equaled guanine. This data was crucial in helping them propose the double helix structure of DNA.
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.
