Eukaryotic organelles reproduce sexually, while prokaryotic organisms reproduce asexually B. The cells of eukaryotic organisms have membrane-bound nuclei while the cells of prokaryotic organism do not. C. Eukaryotic organisms need oxygen while prokaryotic organism do not. D. Prokaryotic organisms can make their own food while eukaryotic organisms cannot. E. Eukaryotic and prokaryotic organisms are actually one and the same variation in terminologies can be attributed to exactly ambiguity.

Which of the following is FALSE about spliceosomes? a. In eukaryotic cells are present in the nucleus.   b. Are about the size of a ribosomal subunit.   c. In bacteria, are present in the cytoplasm.   d. Contain RNA and protein.

Bacteria can be found within rocks kilometers below the Earth’s surface   D. All organisms with cells containing a membrane-enclosed nucleus and organelles are eukaryotes, whereas all organisms with cells lacking a membrane-enclosed nucleus and organelles are bacteria

Horizontal gene transfer probably started soon after endosymbiosis. It has resulted in genes being moved from the mitochondrion to the nucleus.      What is a reasonable explanation for why some genes still remain in the mitochondria?    A.  The products of those genes are rapidly damaged and need to be quickly replaced.   B.  The products of those genes are not required for organelle function.   C.  The ability for lateral gene transfer ended about a billion years ago and some genes simply got “stuck” within mitochondria.   D.  The products of those genes are only needed in the mitochondria.
