40. Which of the following statements correctly describes the process of DNA sequencing by chain termination? (A) The enzyme DNA polymerase is used to form a primer that binds to the template DNA. (B) In order to effectively sequence the DNA, the dideoxynucleotides must be present at a higher concentration than the deoxynucleotides. (C) The use of 4 unique fluorescent labels attached to the dideoxynucleotides allows for a single reaction to be run. (D) The dideoxynucleotides lack a 5'-OH and therefore can not serve as acceptors in nucleotide addition (E) Both B and C are correct
