How can you identify a eukaryotic cell
WebCell theory states that all living things consist of cells which are either prokaryotic or eukaryotic. As microscopy has developed, our knowledge of their structure has improved. WebCell cycle analysis of S. cerevisiae indicated that Cdc45 and DDK have a similar execution point, defined as the time at which a protein functions in the cell cycle . Combined with the data regarding the mcm5-bob1 mutant allele, a plausible model is that DDK phosphorylation of MCMs results in an allosteric change in the MCM complex that allows binding of …

WebEukaryotic cells have a nucleus, a membrane-bound chamber where DNA is stored, while prokaryotic cells don't. This is the feature that formally separates the two groups. Eukaryotes usually have other membrane-bound organelles in addition to the nucleus, while prokaryotes don't. Cells in general are small, but prokaryotic cells are really small.
