In contrast, prokaryotes ( bacteria and archaea ) store their DNA only in the cytoplasm.

An infection that does not and will not produce clinically evident impairment of normal functioning, such as the presence of the normal bacteria and yeasts in the gut, is not considered a disease ; by contrast, an infection that is asymptomatic during its incubation period, but expected to produce symptoms later, is usually considered a disease.

In contrast to other species, E. invadens forms cysts in vitro in the absence of bacteria and is used as a model system to study this aspect of the life cycle.

This is in contrast to all other known infectious agents ( virus / bacteria / fungus / parasite ) which must contain nucleic acids ( either DNA, RNA, or both ).

Hindgut fermenters, in contrast to the ruminants, store digested food which has left the stomach in a pouch-like extension of the large intestine called the cecum ( literally " cave "), where the food is digested by bacteria.

This is in contrast to bactericides, which kill bacteria.

It is sometimes referred to as " aseptic meningitis " in contrast to meningitis caused by bacteria.

Archaea are present in the human gut, but, in contrast to the enormous variety of bacteria in this organ, the numbers of archaeal species are much more limited.

Scientists once classified the Firmicutes to include all Gram-positive bacteria, but have recently defined them to be of a core group of related forms called the low-G + C group, in contrast to the Actinobacteria.

In contrast, TSS caused by the bacterium Streptococcus pyogenes, or TSLS, typically presents in people with pre-existing skin infections with the bacteria.

Humans, in contrast to bacteria, acquire folate ( vitamin B < sub > 9 </ sub >) through the diet.

In contrast, if milk already has harmful bacteria, the use-by dates become irrelevant.

In contrast, when polyadenylation occurs in bacteria, it promotes RNA degradation.

In contrast to bacteria, NHEJ in eukaryotes utilizes a number of proteins, which participate in the following steps:

In contrast, anoxygenic photosynthetic bacteria have a substance called bacteriochlorophyll-which absorbs predominantly at non-optical wavelengths-for light-energy capture, live in aquatic environments, and will, using light, oxidize chemical substances such as hydrogen sulfide rather than water.

By contrast, the sulfate-reducing bacteria considered here reduce sulfate in large amounts to obtain energy and expel the resulting sulfide as waste ; this is known as dissimilatory sulfate reduction.

This was in contrast to bacteria microorganisms, which were retained by the filter.

In contrast, a metal coupon Af in size would have a magnitude from 100,000 to a million less.

In he's hurting himself more than he's hurting you both himself and you have stronger stress than they would ordinarily have if there were no contrast.

We have a brief glimpse of the Tsar's public personality, the `` official Boris '', but our real focus is on the excitement of the crowd -- a significant contrast with its halfhearted acclamation in the opening scene, its bitter resentment and fury in the final act.

In contrast, the morphologically similar seeds of Liliales have no phytomelan, and usually retain a cellular structure in the inner portion of the seed coat.

In contrast, digital signals have a finite resolution.

They are also thought to have pioneered the modern alto format of viola, in contrast to older tenor violas, but this stating is not correct since Gasparo made violas from altos of 39 to tenors of 44, 7 cm.

Brown ( New World ) archaeoastronomers in contrast have abundant ethnographic and historical evidence and have been described as ' cavalier ' on matters of measurement and statistical analysis.

In contrast most synthetic polymers have much simpler and more random ( or stochastic ) structures.

Indic languages, such as Hindi, typically have a four-way contrast among plosives and affricates ( voiced, breathy voiced, tenuis, aspirated ) and a two-way contrast among nasals ( voiced, breathy voiced ).

In some Bantu languages, historically breathy-voiced stops have been phonetically devoiced, but the four-way contrast in the system has been retained.

In contrast Catholics, Orthodox Christians and Arminian Protestants believe that the exercise of free will is necessary to have faith in Jesus.

Its unique relief carvings have a naive dynamic quality that contrast with the rigidity of the figures typical of some other periods.

* Machine heads at the headstock of a classical guitar point backwards — in contrast to most steel-string guitars, which have machine heads that point outward.

In contrast to volcanic craters, which result from explosion or internal collapse, impact craters typically have raised rims and floors that are lower in elevation than the surrounding terrain.

By contrast, the Europeans never infused it into their general diet, but have compartmentalized its use to sweets and desserts.

In contrast, relatively few crannogs have been excavated since the Second World War, although this number has steadily grown, especially since the early 1980s and may soon surpass pre-war totals.

Korean nationalists have virulently reacted against China's application to UNESCO of Goguryeo tombs in Chinese territory: the absolute independence of Goguryeo is a central aspect of Korean identity, because according to Korean legend, it was comparatively independent from China and Japan, in contrast to subordinate states like the Joseon Dynasty and the Korean Empire.

Kant, by contrast, pushed the employment of a priori metaphysical claims as requisite, for if anything is to be said to be knowable, it would have to be established upon abstractions distinct from perceivable phenomena.

On the other hand, CRT monitors have superior contrast, have superior response time, are able to use multiple screen resolutions natively, and there is no discernible flicker if the refresh rate is set to a sufficiently high value.

However, recent investigations of languages with very complex click systems such as Nǁng have revealed that the supposed velar – uvular contrast is actually a contrast of a simple clicks versus click – plosive airstream contours ( or consonant clusters, depending on analysis ).
