Which of the following best describes the findings of the Meselson-Stahl experiment conducted in 1958 to study DNA replication in E. coli?
1
DNA replication is conservative, where one daughter DNA helix consists entirely of old strands, and the other consists entirely of newly synthesized strands.
2
DNA replication is dispersive, meaning segments of old and new DNA are interspersed in both strands of each daughter DNA helix.
3
DNA replication is semiconservative, where each daughter DNA molecule consists of one old strand and one newly synthesized strand.
4
DNA replication is completely random, with no predictable pattern in the distribution of old and new DNA strands in daughter DNA molecules.
