Question

Why ribosomes subunits 40s and 60s form 80s instead of 100s​

Answer 1

$\bigstar$The same way an eukaryotic ribosome has a large sub-unit that sediments at 60s, a small one that sediments at 40s, but the whole structure sediments at 80s, not 100s. ... Essentially the sedimentation coefficient serves to normalize the sedimentation rate of a particle by the acceleration applied to it.

Answer 2

Answer:

"s" means sedimentary rate sedimentation coefficients in Svedberg units of ribosome in centrifugation machine.

if you split the both half....you will get the smaller part in 40s and larger part in 60s.....but collectively they settled down in centrifuger in 80s....this occur due to their combination of small and large subunits
