Rosalind franklin is famous for which contribution to the study of dna? a)creation of an accurate model of dna structure. b)creation of an x-ray diffraction image of dna structure. c)identification of a pattern in ratios of dna bases. d)identification of dna in bandages that contained pus.

The right answer is B

After obtaining a PhD in physics-chemistry at Cambridge in the United Kingdom obtained by studying the porosity of carbon structures, Rosalind Franklin uses X-ray diffraction techniques to determine the amorphous structures of carbon, especially those of DNA fibers.

Rosalind Franklin X-ray diffraction DNA images were instrumental in the discovery of the double-helical structure of DNA.

ans.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
