Indicate whether each of the following descriptions better applies to Illumina sequencing (I), Ion Torrent™ sequencing (T), or both sequencing technologies (B). Your answer would be a four-letter string composed of letters B, I, and T only, e.g. IBBB.
( ) It uses fluorescently labeled nucleotides.
( ) It uses PCR-generated copies of DNA.
( ) It is a second-generation sequencing technology and employs a cyclic wash-and-measure paradigm.
( ) It relies on the fidelity of DNA polymerase for its accuracy.
