According to the Egyptian STEM biology syllabus, what is the exact scientific deduction regarding: Chargaff's Rules of DNA Base Pairing?
In any double-stranded DNA molecule, the percentage of Adenine equals Thymine (%A = %T) and Guanine equals Cytosine (%G = %C), with total purines equaling pyrimidines (%A + %G = %T + %C = 50%)
Uracil replaces Thymine in the double helix of nuclear DNA
The percentage of %A + %T always equals 50% in all organisms
Adenine bonds with Guanine via three hydrogen bonds
