The determination of a DNA sequence requires that the bases are identified in a sequential technique that enables the progressive identification of each base in turn. There are three main requirements for this to be achieved. Which one of the following is NOT one of these requirements? Select one: O a. DNA samples to be sequenced should be separated into its most basic building blocks by the use of RNase enzymes. O b. The detection method must permit rapid and accurate identification of the bases. O c. DNA fragments need to be prepared in a form suitable for sequencing. d. The technique used must achieve the aim of presenting each base in turn in a form suitable for identification.
