Question

31, Bacterial translation requires the actions of a sex pilus to insure that DNA is transferred from one cell to another. 32 The first "eukaryotic" cell emerged when an earlier predatory cell tried to eat an acrobic prokaryotic cell much like a modern Gram- negative cell but never digested it. Competent cells are those who have the ability to attach to a piece of naked dsDNA from the exterior environment to their cell wall, transport a single strand into its cytoplasm and undergo recombination if possible 34 Chemolith?trophic bacteria are those who can easily grow on reduced organic matter, stripping electrons off the compound and eventually depositing these electrons on oxygen. 35 Phenotypic taxonomic systems were based on the outward expression of genes of the organisms being classified and often resulted in errors when thinking about the evolutionary relatedness between organisms that were closely linked in that system. 36 The American Type Culture Collection's only reason for existing is its marvelous collections of fossilized bacteria that are often found next to Tyrannosaurus res and other dinosaur skeletons in museums like the American Museum of Natural History and the British Museum. Fermentative wastes can be thought of as being both "Carbon" based, and "Terminal Electron Acceptor" based, as there are no differences between these two types of wastes for cells undergoing fermentation. 37. An oxygenic photosynthetic autotroph is casily grown in the lab by providing it a light source, and large quantities of CO2 necessary for cell growth, and plenty of water, which serves as its source of electrons. 38 39Clonal evolution results in the rapid spread of some newly emerged, mutated trait throughout an entire population of bacterial cells, many of those cells actually being siblings of each other. 40 Carl Woese played an important role helping to change the taxonomic system used by most biologists (and pretty much all microbiologists) by changing the focus of the old Five-Kingdom, phenotypic-based system to a new Five-Domain system that included the monera (bacteria).

Explanation / Answer

Q31:- False

Explanation:- Bacterial Translation need not to transfer DNA from one cell to another.

Q32:- True

Explanation:- First eukaryotic cell emerged through endosymbiosis of prokaryotic cell whic gave rise to Chloroplast and mitochondria.

Q33:- True

Explanation:- competent cells are those bacterial cells which show ability of recombination.

Q34:- False

Explanation:- Chemolithotrophic bacteria grow on inorganic matter (non carbon) not on organic matter.

Q35:- True

Explanation:- phenotypic classification is based on phenotype which is not based on evolutionary relationships.
