Answer: B As proposed originally in 1953 by Watson and Crick, deoxyribonucleic acid (DNA)consists of two long chains of nucleotides.The two nucleotide chains twist around one another to form a double helix, which resembles a spiral staircase.The two chains of nucleotides are held to one another by weak hydrogen bonds between bases of the chains. Microbial genetics provides powerful tools for deciphering the regulation, as well as the functional and pathway organization, of cellular processes. DNA molecules can be extracted from the cell using the extraction techniques and they are then quantified using the agarose gel electrophoresis.
