X Chromosome Silencing Experiment

Caption

Left, a male cell nucleus, in blue, shows in green the Xist RNA coating of the sole X-chromosome (white) that wasn't enough to silence the X-linked genes in red when researchers artificially tried to silence the sole X. Right, in a female cell nucleus, on the other hand, the Xist RNA coating silences the genes on the second white X chromosomes -- because genes on the first, already silent, X were able to aid the process.
