ribosomes r measured in svedberg units,right?
eukaryotic ribosomes are 80s types
if i am correct 😉
ribosomes have two subunits
40s and 60s subunits
so how come the total is more than 80s ❓
can some one explain what sedimentation coefficient actually is ❓
The unit "S" means Svedberg units, a measure of the rate of sedimentation of a particle in a centrifuge, where the sedimentation rate is associated with the size of the particle. Svedberg units are not additive – two subunits together can have Svedberg values that do not add up to that of the entire ribosome.
Sure, no prob.
There are some organelles that can be measured IN S.U such as mitochondria, microsomes maybe nucleus but not sure. It could be used for gradient seperations that depend on their sedimentation rates. 🙂
