שאלה | Relative to all methylation sites, there was a significant enrichment of "clock sites" in genes that change their expression în response to bacterial infection (LPS). Why do you think that such immune system genes were enriched in "clock sites"?

Relative to all methylation sites, there was a significant enrichment of "clock sites" in genes that change their expression în response to bacterial infection (LPS). Why do you think that such immune system genes were enriched in "clock sites"?

		Since DNA methylation was profiled in white blood cells, which are part of the immune system
		Since diseases shorten life expectancy and are memorized by the immune system.
		Since there are many immune system genes, their chances are higher to include a "clock site".
		Since Amboseli baboons suffered many disease outbreaks that are memorized by their epigenetic marks.
