In eukaryotic cells, can many ribosomes make polypeptides from a single RNA? Is the RNA and DNA polymerase in prokaryotes and eukaryotes the same? If not what are the differences? Explain the following term: Prokaryotic DNA. Do humans have both RNA and DNA?
Prokaryotes are simple, small (1-10 µ in size) and primitive type of cells. Prokaryotic cells consist of no 'well defined nucleus' and the genetic material is found scattered within the cytoplasm of cell, called nucleoid. ... Since,prokaryotes do not have nucleus, they don't have nucleo...
Prokaryotic cells do not have nuclei or membrane-bound organelles. 90 percent of bacteria do, however, havecell walls, which, with the exception of plant cells and some fungal cells, eukaryotic cells lack. These cell walls form the outermost layer of bacteria and make up part of thebacterial ...
Why do mitochondria have their own DNA? Why does a retrovirus copy itself into DNA? Why is gene expression regulated in prokaryotic cells? How does the DNA of prokaryotic cells differ from the DNA of eukaryotic cells? Explain how DNA is used to generate proteins in prokaryotic and eukaryotic ...
You already know that animal cells consist ofa cell membrane, nucleus and a fluid cytoplasm. Do prokaryotes have cytoplasm? Most prokaryotes are small, single-celled organisms that have a relatively simple structure. Prokaryotic cells are surrounded by a plasma membrane, but theyhave no internal mem...
3. All cells come from pre-existing cells. Exceptions to the Cell Theory 1. Viruses are NOT cells, and are NOT made of cells. Virus do not reproduce by division because they are not cells. 2. Mitochondria & Chloroplasts cell parts that have their own DNA and reproduce on their own. (...
More recently, however, other bacterial UbiX such as EcO157UbiX and EcUbiX have been found to accept both DMAP and DMAPP or rely exclusively on DMAPP, thus preferences for DMAP or DMAPP appears not to be linked with the prokaryotic or eukaryotic origin of the enzyme [19]. The UbiX ...
All complex, multicellular organisms are similar in the fact that they are made up of many different types of cells that have specific roles and... Learn more about this topic: Multicellular Organisms | Definition, Pictures & Examples from ...
How do cells use energy? How does bacterial prokaryote reproduction differ from eukaryote (multicellular organisms such as humans) reproduction, in detail? What are the four roles that proteins play in living things? How can prokaryotic cells be smaller than eukaryotic cells and still carry on all...
How do root cells get energy? Energy in organisms is called what? How do humans obtain food energy? How does glucose catabolism serve the organism carrying it out? How do carnivores obtain glucose for cellular respiration? How do fungi digest their food?
