Chargaff rule: The rule that in DNA there is always equality in quantity between the bases A and T and between the bases G and C. (A is adenine, T is thymine, G is guanine, and C is cytosine. The correct answer is option C. Erwin Chargaff dies in the year 2002. The quiz requires you to be familiar with Chargaff's contributions to science. What are the base pairing rules? In DNA, there are four nitrogenous bases: adenine (A), thymine (T), cytosine (C) and guanine (G). In DNA, base pairing between two strands of the duplex. DNA is made up of four nucleotide bases, each of which pairs with only one of the other bases. Chargaff's rules state that DNA from any species of any organism should have a 1:1 stoichiometric ratio (base pair rule) of pyrimidine and purine bases and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine.This pattern is found in both strands of the DNA. The rigorous validation of the rule constitutes the basis of Watson-Crick pairs in the DNA double helix. 's' : ''}}. Chargaff’s rule (the equivalence rule): He found out that in DNA, the concentration of adenine always equalled the concentration of thymine and the concentration of guanine always equalled the concentration of cytosine ie. The quiz will challenge your understanding using both theoretical and practice problems. The base pairing rules means that A always pairs with T, and G always pairs with C ie. The rule was published in 1950 by the Austrian-American biochemist Erwin Chargaff (1905–2002). Enrolling in a course lets you earn progress by passing quizzes and exams. In this exercise, you will apply Chargaff's rules to predict the composition of nucleotide bases in a genome. If one strand of a DNA molecule has the base sequence ATTGCAT, its complementary strand will have the sequence.
