Question

In the dispersive model of DNA replication, both strands of both daughter DNA molecules would consist of:

Options

• Only parental nucleotides

• Entirely new nucleotides

• One complete old strand and one new strand each

• Mixtures of old and new nucleotide segments

Answer 1

The dispersive model hypothesized that DNA replication would result in daughter molecules where both strands contained alternating segments or a mixture of original and newly synthesized material. This model was disproved by experimental evidence.
