Here we are going to see a question which say rosalind flanquin contribution to the understanding of the structure of dna includes discovery of transforming factor, discovery that in the dna of numerous species, she discovered x -ray diffraction evidence, she constructed a ball and stick model.
00:21
The second question in this only, the experiment that determined dna contained the same percentage of the adenine basis as a thymine basis and the same amount of the guanine.
00:32
Basis as cytosine basis was accomplished by the modest wilkins using x -ray diffraction was done by edwin chargerow was done by watson and greek and was done by griffith.
00:44
We have to select the most appropriate answer.
00:48
So moving ahead with the answer we will start with the introduction part and that's the nucleic acids are an essential component of our body are an essential component of our body of our body that place distinct vital functions that place distinct vital functions that are a part of distinct that are a part of distinct that vital that are a part of distinct vital function in the body.

Moving ahead with the explanation portion, moving ahead with the explanation portion in the rosen and flanquin contribution based question, in the structure of dna based question, which is the first one, structure of dna based question.
02:38
Question we will be seeing the explanation in two parts structure of dna based question and and the second one is in which the percentages of the nitrogenous bases are asked percentages of the nitrogenous basis are of the dna basis are asked so firstly we will see the correct answer of the structure of dna question the options see options see in this one in the structure of dna which rosalind flan can contributed option c is correct option c is option c is correct in which rosalind or she provided x -ray diffraction evidence x -ray defraction x -ray defraction x -ray defrax x -3 diffraction evidence of more than one strand of more than one dna strand, more than one strand, more than one strand, and predicted that it was, and predicted, and predicted, the structure is helical, and predicted is helical, is helical...
