Cell walls are a crucial structure of plant life, protecting cells from damage, giving plants shape, and containing ...
Some of the body's cells stay put for life, while others are free to roam. To move, these migratory cells rely on filopodia—sensitive, finger-like protrusions that reach out from the cell membrane ...
A system once tied to DNA organization in cyanobacteria has evolved into a structure that shapes the cell itself. This shift ...
Life and death are traditionally viewed as opposites. But the emergence of new multicellular life-forms from the cells of a dead organism introduces a “third state” that lies beyond the traditional ...
Billions of years of evolution have made modern cells incredibly complex. Inside cells are small compartments called organelles that perform specific functions essential for the cell’s survival and ...
Life’s fundamental structure is the cell, and so the main things that a cell does — processing biomolecules, growing, replicating its genetic material and producing a new body — are considered ...
Long known as a messenger within cells, RNA is increasingly seen as life’s molecular communication system — even between organisms widely separated by evolution. For a molecule of RNA, the world is a ...
