Answer:
This question lacks options, options are: A) DNA replication is semiconservative. B) DNA replication is conservative. C) RNA synthesis is conservative. D) DNA replication is not conservative. The correct answer is A.
Explanation:
Watson and Crick proposed the semi-conservative hypothesis (later demonstrated by Meselson and Stahl in 1957), according to which new DNA molecules formed from an old one have an old and a new strand. This replication model assumed that the double helix DNA separates its two strands and each one serves as a template to synthesize a new strand following the complementary rules of nitrogenous bases. This model was called Semiconservative, since the two newly synthesized double helices have an old strand (an old half) and a new strand (a new half).
