Answer:
E. Gene is amplified by multiplication of cloning host
Explanation:
PCR is a very powerful technique that can help us to amplify exponentially one gene from a very small sample of DNA.
As seen in the attached image, the process begins with a single DNA molecule, for the first cycle, that DNA molecule denaturalizes into two strands, the primers bind to their complementary sides and then the DNA polymerase builds the new DNA strands. The number of copies of the gene that can be obtained with each cycle are 2ⁿ copies, where n is the cycle number. 
 
        
             
        
        
        
Lactic fermentation occurs in many organisms, but only during a specific process known as anaerobic respiration. Muscles usually receive energy through a process known as cellular respiration[15], but when there is a lack of oxygen in the organism, muscles go through anaerobic respiration.
