What kind of data on DNA structure was gathered by Rosalind Franklin and Maurice Wilkins? a. 3D model b. X-ray diffraction pattern data Oc Relative ratios of nucleotides across species d. Poly.A tail composition
Who were the guys who figured out the structure of DNA? What did Rosalind Franklin contribute to the discovery? How do the bases pair in DNA? How did Franklin’s X-ray image and Chargaff’s rule help? What function do the telomeres seem to serve? For what do we use genetic engineering?
22) Rosalind Franklin used X-ray crystallography to show the structure of DNIA and published her oun poper describing this structure the same year as ether Scientists What is the contreveray discovery?

Question 3 0. The X-ray diffraction work of Franklin and Wilkins showed that DNA contains four types of bases. O is composed of nucleotides. O is a double helix, contains hydrogen bonds between bases.
Which of the following statements is true regarding the discovery of the double helix? Choose 1 answer: (A) It was discovered that double-stranded DNA is a parallel molecule. Rosalind Franklin's x-ray crystallography provided Watson and Crick with important data that helped determine the structure of DNA. The experiments that led to the discovery of the double helix ultimately disproved Chargaff's rules regarding nitrogenous bases. James Watson, Francis Crick, Maurice Wilkins, and Rosalind Franklin were awarded the Nobel Prize in Medicine...
Watson and Crick A. Determined the mode of DNA replication Rosalind Franklin B. Discovered the four DNA nucleotides: A, T, C, G Meselson and Stahl C. Determined the ratios of nucleotides in DNA Edwin Chargaff D.Used X-ray crystallography to determine the 3- Dimensional structure of DNA E. Proposed a double helix model of DNA F. Proposed a triple helical model of DNA
Rosalind Franklin spent countless hours in the lab solving the structure of DNA. We know that X-rays cause DNA to break in half. A) Which of the following chromosomal rearrangement likely occurred in her cells: deletion, duplication, inversion, or translocation? B) Explain how this could lead to a position effect on gene expression.
Chargaff discovered that the A-T bond has the same width as the G-C bond. What implication does this have for the structure of the DNA molecule? It means that the molecule will vary in width as you move down its length, depending on the number of A-T and G-C nucleotides. It means that the molecule will be very hydrophilic, because nucleotides are hydrophilic. It means that DNA was the first life form on Earth. It means that the molecule will...
