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 ...
During early development, tissues and organs begin to bloom through the shifting, splitting, and growing of many thousands of ...
In order for HIV to replicate, the viral genome must enter into the cell nucleus and integrate into the host cell chromosome. Previous work suggests that the entry proceeds through nuclear pore ...
