A methyl group is a basic unit in organic chemistry: one carbon atom attached to three hydrogen atoms. When a methyl group attaches to a specific spot on a gene - a process called DNA methylation - it can change the gene's expression, turning it off or on, dampening it or making it louder.

That led to the appointment of Detroit's first black police chief and, eventually, the suspension of a unit known for harassing young black men. Cockrel helped her husband win a city-council seat, and he was viewed as a leading potential successor to Young. But in 1989, Ken had a heart attack and died. For a while, Sheila stayed home to care for her young daughter. Four years...
