Question

Which of the following identifies an incorrect model of DNA’s semiconservative nature?

Figure C is incorrect because as DNA replicates it uses the original strand of DNA as a template resulting in molecules of DNA that have half the original strand of DNA and half new DNA.


Figure B is incorrect because as DNA replicates it makes an exact copy of each strand, resulting in one new molecule of DNA and the original molecule of DNA.


Figure D is incorrect because as DNA replicates it makes an exact copy of each strand, resulting in one new molecule of DNA and the original molecule of DNA.


Figure A is incorrect because as DNA replicates it uses the original strand of DNA as a template resulting in molecules of DNA that have half the original strand of DNA and half new DNA.
