When Chargaff was performing his experiments, the tetranucleotide hypothesis, which stated that DNA was composed of GACT nucleotide repeats, was the most widely accepted view of DNA’s composition. How did Chargaff disprove this hypothesis?
A student has drawn an enlarged portion of a DNA “ladder” model to show two of the nucleotides in greater detail (in the same orientation as they would occur in the ladder model). Which two nucleotides did the student draw?
How did Griffiths and Avery discover that DNA was the molecule of heredity? Would we have been able to discover the structure of DNA without this work? Why or why not? Would we have been able to understand or actually try to understand DNA replication without his work? Why or why not?
