Cell Compartmentalization. One of the major differences between eukaryotes and prokaryotes is that eukaryotes compartmentalize their internal processes in membrane-bound organelles. In eukaryotic cells, after RNA is made from DNA in the process of transcription, it moves to the ribosome to go through the process of translation.-2-AP® BIOLOGY EQUATIONS AND FORMULAS x = sample mean n = size of the sample . s = sample standard deviation (i.e., the sample-based estimate of the standard deviation of the population) o = observed results. e = expected results . Degrees of freedom are equal to the number of distinct possible outcomes minus one.
