Humans have 46 chromosomes, and each one is capped at either end by repetitive sequences called telomeres. If you ask a biologist if humans have circular DNA, they are likely to say 'no.' That is because eukaryotic cell nuclei ...
Almost every cell in the human body, from beating heart cells to bacteria-gobbling immune cells, is powered by chemical energy produced by specialized organelles called mitochondria. The process of energy generation creates ...

If there's one fact that most people retain from elementary biology, it's that mitochondria are the powerhouses of the cell. As such, they break down molecules and manufacture new ones to generate the fuel necessary for life. ...
