Because such strains transfer chromosomal genes very efficiently they are called Hfr ( high frequency of recombination ).

Because a large portion of the active species is lost to recombination, process times may take longer.

Because the desired type of DNA recombination is a rare event in the case of most cells and most constructs, the foreign sequence chosen for insertion usually includes a reporter.

Because all mitochondrial DNA ( mtDNA ) is generally passed from mother to offspring without recombination, all mitochondrial DNA ( mtDNA ) in every living person is directly descended from hers by definition.

Because in sexual reproduction, genetic recombination ensures that with each generation, only half the genetic material of a parent is represented in the offspring, some genetic lines may die out entirely, even though there are numerous progeny.

Because the only humans which have a Y chromosome are males, the genes are simply passed from father to son, with no interchromosomal genetic recombination.

Because the photon carries relatively little momentum, radiative recombination is significant only in direct bandgap materials.

Because of this tendency for chromosomal crossover, the DSBR pathway is a likely model of how homologous recombination occurs during meiosis.

Because of the means of publication -- science-fiction magazines and cheap paperbacks -- and because dystopian science fiction is still appearing in quantity the full range and extent of this phenomenon can hardly be known, though one fact is evident: the science-fiction imagination has been immensely fertile in its extrapolations.

Because the bobbin-to-cone winding process is a relatively high-cost operation for the mill, the almost complete automation provided by the Uniconer can mean important economies in textile production, at the same time upgrading quality.

Because if you can't then nobody else can either, nobody else can have him.

Because oxygen concentration in the water increases at both low temperatures and high flow rates, aquatic amphibians in these situations can rely primarily on cutaneous respiration, as in the Titicaca water frog and the hellbender salamander.

Because and can be very similar numbers, the precision of the result can be much less than the inherent precision of the floating-point arithmetic used to perform the computation.

Because the percentage of each constituent can be varied, with any mixture the entire range of possible variations is called a system.

Because of the quantum mechanical nature of the electrons around a nucleus, atomic orbitals can be uniquely defined by a set of integers known as quantum numbers.

Because an alpha particle is the same as a helium-4 nucleus, which has mass number 4 and atomic number 2, this can also be written as:

: Because of associativity, the grouping parentheses can be omitted without ambiguity.

Because ending the game is optional, and a player may not realize that he can end it, it is unethical to say " good game ", or in any other way indicate that the game could be ended, until after a player actually has ended the game.

Because it is innervated by preganglionic nerve fibers, the adrenal medulla can be considered as a specialized sympathetic ganglion.

Because of the wide variety of evidence, which can include artefacts as well as sites, there is no one way to practice archaeoastronomy.

Because individuals with albinism have skin that entirely lacks the dark pigment melanin, which helps protect the skin from the sun's ultraviolet radiation, their skin can burn more easily from overexposure.

Because of the medical problems that can be caused by withdrawal, alcohol detoxification is carefully controlled and may involve medications such as benzodiazepines such as diazepam ( Valium ).

Using Zorn's lemma, it can be shown that every field has an algebraic closure, and that the algebraic closure of a field K is unique up to an isomorphism that fixes every member of K. Because of this essential uniqueness, we often speak of the algebraic closure of K, rather than an algebraic closure of K.

Because the differences between the prices are likely to be small ( and not to last very long ), this can be done profitably only with computers examining a large number of prices and automatically exercising a trade when the prices are far enough out of balance.

Because brass is not ferromagnetic, it can be separated from ferrous scrap by passing the scrap near a powerful magnet.

Because of his widespread correspondence with others throughout the British Isles, and due to the fact that many of the letters imply that Bede had met his correspondents, it is likely that Bede travelled to some other places, although nothing further about timing or locations can be guessed.

Because breasts are mostly fatty tissue, their shape can within limits be molded by clothing, such as foundation garments.

Because bipolar disorder can have a high rate of both under-diagnosis and misdiagnosis, it is often difficult for individuals with the condition to receive timely and competent treatment.

Because of this, is usually a more effective choice under these operating systems ; sensitivity for these two combinations can be enhanced by the CONFIG. SYS statement.

Because the ancients could not produce temperatures high enough to melt iron fully, the production of steel in decent quantities did not occur until the introduction of blister steel during the Middle Ages.

Because of this risk, patients prescribed clozapine may need to have regular blood checks to catch the condition early if it does occur, so the patient is in no danger.

Because the sun's mean motion was used to calculate the jieqi, or seasonal markings, until 1645, this intercalary month was equally likely to occur after any month of the year.

Because the orbital plane of the Moon is tilted with respect to the orbital plane of the Earth ( the ecliptic ), eclipses can occur only when the Moon is close to the intersection of these two planes ( the nodes ).

Because children attend school longer now and have become much more familiar with the testing of school-related material, one might expect the greatest gains to occur on such school content-related tests as vocabulary, arithmetic or general information.

Because of poorly defined lines of responsibility, administrative conflicts often occur between local and national authorities of Goskompriroda and between Goskompriroda and a second national agency, the Hydrometeorological Administration ( Gidromet ), which is the main monitoring agency for air, water, and soil quality.

Because logrolling is pervasive in the political process, it is important to understand which external situations determine when, why, and how logrolling will occur, and whether it is beneficial, efficient, or neither.

Because Malachi's name does not occur elsewhere in the Bible, some scholars indeed doubt whether " Malachi " is intended to be the personal name of the prophet.

Because the oxygen atom that is replaced by F-18 to generate FDG is required for the next step in glucose metabolism in all cells, no further reactions occur in FDG.

Because the body uses gastric acid to release B < sub > 12 </ sub > from food particles, decreased vitamin B < sub > 12 </ sub > absorption may occur with long-term use of proton-pump inhibitors and may lead to Vitamin B12 deficiency.

Because these changes occur very rapidly they define an upper limit on the volume of a quasar ; quasars are not much larger than the Solar System.

Because both ends of the RS-232 circuit depend on the ground pin being zero volts, problems will occur when connecting machinery and computers where the voltage between the ground pin on one end, and the ground pin on the other is not zero.

Because of this, promotion and relegation can occur ; or, in league systems without promotion and relegation, clubs in professional leagues can have a team in the minor leagues.

Because landslides occur frequently and can represent some of the most destructive forces on earth, it is imperative to have a good understanding as to what causes them and how people can either help prevent them from occurring or simply avoid them when they do occur.

Because the peak neutron flux and fission reaction rates would occur outside of the vehicle, these activities could be much more vigorous than they could be if it was necessary to house them in a vessel ( which would have temperature limits due to materials constraints ).

) Because each league will have an odd number of teams, interleague play will occur throughout the season, so that every team will be able to play every day.

Because the pointer of the meter is usually a small distance above the scale of the meter, parallax error can occur when the operator attempts to read the scale line that " lines up " with the pointer.

Because pink noise has a tendency to occur in natural physical systems it is often useful in audio production.

Because of this, identifier / reserved word collisions can occur when code implemented in one language tries to execute code written in another language.

Because of the Great Salt Lake's high salinity, it has few fish, but they do occur in Bear River Bay and Farmington Bay when spring runoff brings fresh water into the lake.

Because the " parity " bit is optional, this error will not occur if parity has been disabled.

In the presence of the static, uniform external magnetic field, the Hamiltonian for the absorbing center takes the form Ĥ = Ĥ < sub > 0 </ sup > + Ĥ < sub > 1 </ sup > which is parallel to the direction of the propagation of the electric field k. Because the transition occur between the two eigenstates of Ĥ < sub > 0 </ sub >, a and j, the absorption and the CD intensity are determined as follows:

Because earthquakes can only occur when a rock is deforming in a brittle fashion, subduction zones can create large earthquakes.

( Fig 1B ) Because the buoyancy of the relatively light continental crust is likely to prohibit its extensive subduction, a flip in subduction polarity will occur yielding an ophiolite sheet lying above a descending plate.
