Question 16
What does 'S' refer in a 70S and 80S ribosome?
'S' refers to Svedbergs unit for sedimentation coefficient. Sedimentation coefficient depicts that how fast a cell organelle sediments during the ultracentrifugation.
In cells heavier the structure, higher is the sedimentation coefficient.
The value of S is equal to 10−13 seconds (1 s = 1×1= −13 seconds).
