QUESTION 28 3.0 All of the following statements about the Illumina (reversible terminator) process for carrying out Next Generation Sequencing (NGS) are true EXCEPT: O A. The template is fragmented into small oligonucleotides with read lengths of 400-500 nucleotides. O B. The template fragments are attached to a glass slide where they are amplified by PCR.
