Rosalind Franklin's X-ray crystallography data suggested DNA is double stranded and has a uniform diameter. These observations can be used to rule out base pairing between two of the same nucleotide because . thymine dimers are removed by excision repair the antiparallel orientation of strands would result in one of the pair being upside down an A-A pair is wider than a C-C pair identical nucleotides would not have the appropriate number of hydrogen bonding sites to pair

the answer would be b

explanation:

the answer to your question is:

c. complementary base-pairing

the generally accepted parts of modern cell theory include: all known living things are made up of one or more cells. all living cells arise from pre-existing cells by division. the cell is the fundamental unit of structure and function in all living organisms.

the principles and empirical processes of discovery and demonstration considered characteristic of or necessary for scientific investigation, generally involving the observation of phenomena, the formulation of a hypothesis concerning the phenomena, experimentation to test the hypothesis, and development of a conclusion that confirms, rejects, or modifies the hypothesis.
