But they do not have a cell membrane or other organelles (for example, ribosomes or mitochondria) that cells have. Living things reproduce. Do viruses have feelings? *Viruses and cells don't actually have preferences, thoughts or feelings. Do viruses have movement? Due to their simple ...
We’ll read more about mitochondrial DNA later in this chapter. Genetic data tell us there is no such thing as “race”. At least, not in the way most people think about it, which is a few very simple categories. Instead, genetically speaking, there are only ethnic subgroups or common ...
similar to germ granules. The detailed composition of glial granules will need to be determined to characterize the role of the granules in the brain; however, our current data suggest a remarkable conservation of the assembly mechanisms of large dynamic membraneless organelles in brain and germline...

There are two main types of cells, eukaryotes and prokaryotes. Eukaryotes are cells that have a nucleus and membrane-bound organelles and include plants, animals and fungi. Prokaryotic cells do not have a nucleus or membrane-bound organelles and include all bacteria....
