The first major evidence for the existence of prevalent clonal hematopoiesis in healthy people was put forth in the 1990s. Using the HUMARA assay, scientists found that there was nonrandom X-inactivation of the X chromosome in the blood of some healthy women. This means that a greater than expected proportion of the blood had the silencing of one specific X chromosome in the chromosome pair. Just as the observation of the same DNA mutation in a subset of cells sugge… WebApr 5, 2024 · Building on earlier research of the CRISPR-Chip, the researchers used electronic transistors made from graphene to detect genetic mutations in minutes. DNA samples are placed on the chip, and thousands of CRISPR molecules scan for specific mutations. If CRISPR binds with the target, it creates an electrical charge that is …
