New findings from Vrije University in the area of cell biology described
August 14th, 2007
Scientists discuss in "Viral capsids: mechanical characteristics, genome packaging and delivery mechanisms" new findings in cell biology. "The main functions of viral capsids are to protect, transport and deliver their genome. The mechanical properties of capsids are supposed to be adapted to these tasks," scientists in Amsterdam, Netherlands report. "Bacteriophage capsids also need to withstand the high pressures the DNA is exerting onto it as a result of the DNA packaging and its consequent confinement within the capsid. It is proposed that this pressure helps driving the genome into the host, but other mechanisms also seem to play an important role in ejection. DNA...
