Explanation:
Anabolism is a metabolic process that uses up energy that is produced to build up complex and larger molecules from smaller ones. It is part of the chemical process that takes place in a cell.
For example, photosynthesis is an anabolic process, in which the cell forms larger molecules such as glucose from smaller molecules like water and carbon dioxide, with the use of solar energy.

The correct answer is B. the two strands of DNA must separate.
Explanation:
DNA is a double-stranded structure. The two strands are joined together by the formation of hydrogen bonds between complementary nucleotides. So before the replication takes place these two strands must be separated.
The separation of DNA strand is accomplished by the action of a helicase enzyme which breaks the hydrogen bond between complementary nucleotides and separated the two DNA strands.
After separation, the DNA polymerase binds to separated DNA and replicating the DNA. So the right answer is B.
