Free living bacteria do meet their energy needs by their own but in obligate parasites, they purely depends on host for their energy and nutrient requirements. Therefore free-living bacteria will have a large amount of gene than that of intercellular parasitic bacteria
so the given statement is FALSE
Add Answer to:
A bacterium that is an obligate parasite inside eukaryotic cells will have a larger genome than...

1) When comparing the genome of a prototypic bacterium such as E.coli, and the genome of a human, which of the following statements is true? a. The genome of E.coli is a single, circular, double stranded piece of DNA; the human genome is comprised of several linear chromosomes b. The genome size of E.coli is approximately 4.5 x 106 base pairs; the size of the human genome is approximately 3.2 x 109 base pairs c. The genome size of E.coli...

Question 78 Which of the following statements about the cytoskeleton is TRUE? All eukaryotic cells have actin, microtubules, and intermediate filaments in their cytoplasm The cytoskeleton provides a rigid and unchangeable structure important for the shape of the cell. The three cytoskeletal filaments perform distinct tasks in the cell and act completely independently of one another Actin filaments and microtubules have an inherent polarity, with a plus end that grows more quickly than the minus end С. D Question 79...

If a eukaryotic organism did not have a functional telomerase, what would you predict to be true about this organism? a reduction in chromosome length in reproductive cells (gametes) production of a larger number of Okazaki fragments than eukaryotes that possess telomerase high sensitivity to sunlight inability to correct DNA mutations a high probability of somatic cells becoming cancerous

4. Development of organelles Aa Aa 3 Modern eukaryotic cells are very complex and have many features that allow them to function efficiently. These complexities took a very, very long time to evolve and likely progressed as a series of small improvements that were naturally selected. For example, modern eukaryotic cells have internal membranes surrounding their organelles and the nucleus. This arrangement likely arose when the cellular membranes of some ancient bacterial cells accidentally folded to become internal membranes. Which...

transformed eukaryotic cells utilize glucose at a higher rater than normal cells. you have isolated two transformed cell lines (a and b) and incubate cell homogenates with glucose labeled with C14 in the 1,3,4, or 6 positions to measure the initial rates of the radioactive labeled CO2 production. If cell line A metabolizes glucose primarily by the HMP shunt, and cell line B metabolizes glucose primarily by glycolysis, what will be the pattern of the radimetrically labeled CO2 formation from...
