Question

When one DNA molecule is replicated, the result is two DNA molecules. What is true of the second DNA molecule? A. It is identical or nearly identical to the first DNA molecule. B. The sequence of bases, from top to bottom, is opposite the sequence in the first DNA molecule. C. It is half the size of the first DNA molecule. D. It is twice the size of the first DNA molecule.

Answer 1

Answer: it is identical or nearly identical to the first DNA molecule.

Explanation: The process of DNA replication results in an exact copy of the original DNA molecule. This process occurs once in the life-cycle of a cell, allowing the cell to divide into two cells with identical DNA copies. Rarely, a mistake occurs during some part of the process. These mistakes are called mutations, and will result in a slightly different strand of DNA.

Answer 2

It is identical or nearly identical to the first DNA molecule.
