Answer: Nucleotides are the monomers used for DNA synthesis. The mix also contains a template, DNA taq polymerase, buffer, reverse and foward primer and magnesium ions.
Explanation: 
A PCR master mix is a premixed solution that has all of the components for a Polymerase chain reaction (PCR). This reaction is a laboratory technique that amplifies small fragments of DNA into millions of copies.
The master mix used for that contains dNTPs (nucleotides). In the DNA there are four types of nucleotides that are differentiated by the nitrogen base they have: adenine (A), guanine (G), cytosine (C) and thymine (T).
<u>Since nucleotides are the monomers that make DNA, they are found in the mix because they are the material for DNA synthesis.</u> 
The reaction mixture also requires;
- DNA template, the sequence of DNA to be amplified
- DNA taq polymerase, a heat resistant enzyme that assembles nucleotides into a new DNA
- Salt buffer, for an optimum ionic environment and pH
- Oligonucleotide primers (reverse and foward), pieces of DNA complementary to the template. Each hybridizes with one of the DNA chains.
- Magnesium ions, a catalyst required by DNA polymerase to work
 
        
             
        
        
        
The right answer is the second one
        
                    
             
        
        
        
A part of the definition of binary fission is "splitting in half." It is an asexual form of reproduction, one turns in to two. This is choice B.
        
                    
             
        
        
        
Answer:
D. It can function independently
Explanation:
A. Not a haploid, the daughter cell is going to be a diploid cell, because it is a body cell, not a sex cell; they are suppose to have the same amount of chromosomes as the parent cells.
B. It will go through cytokineses ( last step of the mitosis) the cells will not be connected to parent cell and is independent (D)
C. Inside the chromosomes, no matter it is a haploid or diploid cell, it will contain DNA.  
D. After going through the cell cycle, the new daughter cell produced will be a new individual and do not connect to other cells.
