Color-Coded Cells Reveal Patchwork Patterns of X Chromosome Silencing in Female Brains
Researchers color-coded cells in female mice to display which of their two X chromosomes had been “silenced.”
Producing brightly speckled red and green snapshots of many different tissues, Johns Hopkins researchers have color-coded cells in female mice to display which of their two X chromosomes has been made inactive, or “silenced.” Read the full release here.
Jeremy Nathans, professor of molecular biology and genetics:
"Calico cats, which are only ever female, have mottled coat colors. They have two different versions of a gene for coat color, which is located on the X chromosome: one version from their mother and the other from their father."
