What did Chargraffs rule state?
Basically chargoffs rule, of i all know, Thymine equals the Adenine, Cytosine equals the Guanine, and something else about the pyrmine. - nikkiYes, Nikki is close and she has the right idea. Erwin Chargraff, an American biochemist, had discovered that the percentages of guanine (G) and cytosine (C) bases are almost equal in any sample of DNA. But the same thing is true for the other nucleotides, adenine (A) and thymine (T). (A) = (T) and (G) = (C) became known as Chargraff's rules. - bradberrya
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!
What did chargraff discover?
The American biochemist Erwin Chargaff discovered that DNA is the primary constituent of the gene, thereby helping to create a new approach to the study of the biology of heredity.
What did chargraff discover about the frequency of the nucleotides?
Chargaff discovered that in DNA, there is a 1:1 ratio of adenine and thymine, and a 1:1 ratio of guanine and cytosine. This led to the rule that adenine always pairs with thymine and guanine always pairs with cytosine.
When was Erwin Chargraff born?
Erwin Chargaff was born on August 11, 1905. He was an Austrian biochemist known for his work on the composition of nucleic acids and his contributions to the understanding of DNA. Chargaff's rules were pivotal in the discovery of the double helix structure of DNA. He passed away on June 1, 2002.
