Question

Why did scientists synthesized light and heavy dna in messelson and stahl?

Answer 1

the answer is


model of DNA replication meselson and stahl experiment

key points
1. there were three models for how organism might replicate their DNA semiconservative, conservative and dispersive.
2. the semiconservative model, in which each strand of DNA serve as a template to make a new, complementary strand, seemed most like based on DNA structure.
3. the model was tested by meselson and stahl who label the DNA of bacteria cross generation using isotopes of Nitrogen.
4. from the patterns of DNA labelling they saw meselson and stahl confirm that DNA is replicated semiconservative.

They allowed the synthesis of light and heavy DNA molecules in order to create observable differences in parent and newly synthesized DNA strands based on differences in the density.
