NettetProkaryotes are always unicellular, while eukaryotes are often multi-celled organisms. Additionally, eukaryotic cells are more than 100 to 10,000 times larger than prokaryotic cells and are much more complex. The DNA in eukaryotes is stored within the nucleus, while DNA is stored in the cytoplasm of prokaryotes. NettetViral vectors are used to deliver genes to cells. They can either add a gene (knock-in) to study the function of a particular gene or to delete a gene (knock-down) to study the effects of gene deletion or reduction. All work with viral vectors is subject to the NIH Guidelines for Recombinant or Synthetic Nucleic Acids, and as such, all work ...
