- Answer: 32 molecules of DNA would be after four PCR if the initial reaction mixture contained two molecules
- After 'n' rounds of the polymerase chain reaction, it is feasible to produce 2 n DNA molecules from a single DNA template molecule (PCR). Therefore, 2 to the power 4  = 16 DNA molecules will be produced after 4 PCR cycles
-  If two molecules are doubled four times, 32 DNA molecules are created.
Explanation:
The PCR method is what?
The highly sensitive PCR method enables quick DNA amplification of a particular section. Using visual methods based on size and charge, PCR may detect and identify gene sequences by producing billions of copies of a certain DNA fragment or gene.
 What does a PCR have to accomplish?
A given DNA segment can be quickly multiplied (amplified) into millions or billions of copies using the polymerase chain reaction (abbreviated PCR), allowing for more in-depth analysis.
 What are the three main PCR steps?
 For any DNA synthesis reaction, there are only three easy stages that must be completed: First, the template is denaturated into single strands. Next, primers are annealed to each original strand to synthesise new DNA strands. Finally, the new DNA strands are extended from the primers.

 The answer is Vacuoles. After water enters this cell through the osmosis, it expands to absorb water and contract to release it.
        
             
        
        
        
Xylem moves water from roots to the leaves, and phloem moves food from the leaves to the rest of the plant. During transpiration water evaporates from the leaves and draws water from the roots.
