 Normalize After PCR? The Damage Is Already Done.
Balanced read counts do not necessarily mean better data. Post-PCR normalization, whether bead-based, enzymatic, CRISPR-based, or manual happens after amplification when duplicates, chimeras, and dropouts may already be embedded in the library. Raw counts can look balanced, but quality-filtered usable reads reveal the real picture. Effective normalization starts earlier, during amplification.

Scientists have long understood how these two types of immunity work together in higher organisms but not in the microbial world. | | | | |  Cells can switch off genes by tightly packaging DNA around proteins called histones. | | | | |  A new review explores how advances in understanding X chromosome inactivation (XCI) are creating potential therapeutic opportunities for a range of X-linked genetic disorders, including Rett syndrome, Fabry disease, Duchenne muscular dystrophy, hemophilia, and others. | | | | |  The main function of CRISPR-Cas systems, the revolutionary tool scientists now employ to edit genes, is to defend bacteria against threats such as viruses called bacteriophages. | |
