454 pyrоsequencing hаs а well-knоwn systemаtic errоr type called "homopolymer errors." What is the molecular basis of this error? A. The luciferase enzyme loses activity after many cycles, producing dim signals for all bases equally B. When multiple identical bases occur consecutively (e.g., AAAAA), multiple pyrophosphates are released simultaneously, producing a proportionally brighter light signal but the signal intensity is not perfectly linear, making it difficult to accurately count runs of 6 or more identical bases C. Homopolymer regions cause secondary structure that stalls the polymerase completely D. Apyrase degrades pyrophosphate in homopolymer runs, suppressing the signal
