DNA, which is a sequence of nucleotides, make up genes. Genes are DNA sequences that  code of a functional protein and are controlled by a promoter region on the DNA. DNA, including genes within it, are supercoiled into chromosomes so they are able to fit in the cell. Otherwise, uncoiled DNA in a cell is much longer than the cell itself.  
 
        
             
        
        
        
The answer is C. This is because nucleotide elongation involves the addition of a nucleotide to the 3 prime carbon of the previous nucleotide carbon ring. This involves a dehydration reaction between the phosphate group on the 5 prime carbon of the last nucleotide to the hydroxyl group of the 3 prime carbon of the previous nucleotide.
