Web24 aug. 2024 · How does DNA exist in prokaryotic cells and eukaryotic cells? A eukaryote contains a well-defined nucleus, whereas in prokaryotes, the chromosome lies in the cytoplasm in an area called the nucleoid. In eukaryotic cells, DNA and RNA synthesis occur in a separate compartment from protein synthesis. WebQuestion 1. Many cells have a cell wall, but animal cells do not. Why might this be? a) Because animal cells only exist in the multicellular form. b) Because animal cells do not need structural support. c) Because animal cells are capable of movement. d) Because animal cells can control osmotic pressure. how many real estate agents in bc
