Researchers have found that the DNA spools inside human cells are far less tightly wound than textbooks have long suggested.
In human cells, there are about 20,000 genes on a two-meter DNA strand—finely coiled up in a nucleus about 10 micrometers in diameter. By comparison, this corresponds to a 40-kilometer thread packed ...
Stretched into a single line, the DNA packed inside one human cell would reach roughly two meters, yet it folds into a ...
Damage to DNA in cancer cells can lead to pieces breaking off chromosomes and floating away, like icebergs cracking off from ...
Every cell in a body contains the same genetic sequence, yet each cell expresses only a subset of those genes. These cell-specific gene expression patterns, which ensure that a brain cell is different ...
A study published in the journal Cell marks the first reported instance of generative AI designing synthetic molecules that can successfully control gene expression in healthy mammalian cells.
