Describe The Discoveries That Led To The Modeling Of Dna. Photograph 51 - the famous X-ray diffraction photograph of DNA taken by Rosalind Franklin DNA was discovered in 1869 but it took until 1943 before scientists realised that DNA was the genetic. His discoveries known as Chargaffs Rules proved that guanine and cytosine units as well as adenine and thymine units were the same in double-stranded DNA and he also discovered that DNA varies among species. Complementary base pairs are added. Chargaff discovered base pairing rules.
Enzyme are proteins with highly specific functions. Describe the discoveries that led to the modeling of DNA.

D Describe the discoveries that led to the modeling of DNA. Complementary base pairs are added. Franklin took X-ray photographs that revealed that DNA has a spiral structure.
From X-Ray photographs by Frank we discovered that DNA is of spiral shape.
Chargaff discovered that adenine and thymine are present in equal proportions and guanine and cytosine are present in equal proportions. Franklin took X-ray photographs that revealed that DNA has a spiral structure. Today he is widely considered to be the father of genetics. James Watson and Francis Crick Getty Images. From that Watson and Crick derived the double helix and complementary base pairing. Chargaffs rule also started the whole new discovery.
