<span>The hypothesis has to survive all attacks on it and continue to provide the best known explanation of the known data.
In the scientific method, there are several steps towards the creation of a hypothesis and eventually a theory.
1. Gather data.
2. Construct a hypothesis that explains the data. This hypothesis should be capable of being disproved and should be capable of making predictions.
3. Gather more data. DO NOT cherry pick only that data which supports the hypothesis . If data is uncovered that contradicts the hypothesis , revise or replace the hypothesis.
4. After the hypothesis has survived all attacks on it and is the best known explanation of the data, then it becomes a theory.
5. Note, data collection continues after the hypothesis became a theory and if new data is discovered that is in conflict with the theory, then the theory is modified, or discarded in favor of a new hypothesis or theory.</span>
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).
