Conservative Vs Semiconservative Model Of Dna Replication. Conservative replication produces two dna helices in which one helix contains entirely old dna and the other helix contains entirely new dna while semiconservative replication produces two helices in which each helix contains one new strand and one old strand. Note that after two rounds two of the dna molecules consist only of new material while the other two contain one old and one new strand.
Thus the old parent double helix would remain unchanged. In this mode of replication out of the two double helices formed one would be entirely of old material parental dna and the other entirely of new material. Conservative replication produces two dna helices in which one helix contains entirely old dna and the other helix contains entirely new dna while semiconservative replication produces two helices in which each helix contains one new strand and one old strand.
Conservative replication produces two dna helices in which one helix contains entirely old dna and the other helix contains entirely new dna while semiconservative replication produces two helices in which each helix contains one new strand and one old strand.
After one round of replication the two daughter molecules each comprises one old and one new strand. Thus the old parent double helix would remain unchanged. After one round of replication the two daughter molecules each comprises one old and one new strand. In this mode of replication out of the two double helices formed one would be entirely of old material parental dna and the other entirely of new material.
