Final answer:

The Illumina/Solexa version of sequencing by synthesis is a next-generation sequencing technique used for rapid DNA sequencing. It involves adding adapters to fragmented DNA and using sequencing enzymes to determine the order of nucleotides and synthesize a new DNA strand.

Step-by-step explanation:

The Illumina/Solexa version of sequencing by synthesis is a next-generation sequencing technique used for rapid DNA sequencing. It involves fragmenting the DNA sample into short fragments and adding DNA adapters to both ends of each fragment. The fragments are then immobilized on beads, amplified by PCR, and placed into wells containing sequencing enzymes. Each nucleotide is added one after the other, and when it is incorporated, pyrophosphate is released, emitting a small flash of light that is recorded by a detector. This allows the order of nucleotides to be determined and the new strand of DNA to be synthesized.
