**Question 15:** How many copies of DNA are produced after PCR is completed?
**Answer:** billions of copies
PCR (Polymerase Chain Reaction) is designed to amplify a specific DNA sequence, resulting in millions to billions of copies of that segment.

**Question 16:** How many copies of DNA are produced after DNA replication in a cell is completed?
**Answer:** one copy
During DNA replication, each single DNA molecule is copied to produce two identical DNA molecules, but the original is not counted as a separate copy. Thus, the total number of distinct DNA molecules in the cell remains at one copy of each original molecule, leading to two total molecules after replication. If you are considering the original plus the new one, you may think of it as producing "one copy" of each molecule. If the question implies looking at the new copies, it could be interpreted differently depending on context, but typically, the phrase "after DNA replication" refers to the end state before they are separated.
