[{'content': 'DNA replication follows which of the following model(s)? \nSelect and explain. \nA. Conservative, B. Semiconservative, C. Dispersive, D. All of the above', 'role': 'user'}, {'content': 'Answer: B \nExplanation: DNA replication follows Semi-conservative model Three models were proposed to explain the DNA replication. Semi-conservative model is experimentally proved. During DNA replication, the DNA double helix is separated. Each strand acts as a template for the synthesis of new, complementary strand. Each of the two DNA molecules produced contains : 1 parent strand 1 daughter strand. Half of the parent strand is conserved, hence the name semi-conserved.', 'role': 'assistant'}]
