One difference between eukaryotic and prokaryotic genes is that eukaryotic genes can contain introns ( intervening DNA sequences ) which are not coding sequences, in contrast with exons, which are DNA coding sequences.

Although the Casimir effect can be expressed in terms of virtual particles interacting with the objects, it is best described and more easily calculated in terms of the zero-point energy of a quantized field in the intervening space between the objects.

It can also deposit from vapour with no intervening liquid phase, such as in the formation of frost.

Although introns are sometimes called intervening sequences, the term " intervening sequence " can refer to any of several families of internal nucleic acid sequences that are not present in the final gene product, including inteins, untranslated sequences ( UTR ), and nucleotides removed by RNA editing, in addition to introns.

Quantum teleportation, or entanglement-assisted teleportation, is a process by which a qubit ( the basic unit of quantum information ) can be transmitted exactly ( in principle ) from one location to another, without the qubit being transmitted through the intervening space.

It agrees that there can be no motion " during " a durationless instant, and contends that all that is required for motion is that the arrow be at one point at one time, at another point another time, and at appropriate points between those two points for intervening times.

Another resolution, of which the Novikov self-consistency principle can be taken as an example, holds that if one were to travel back in time, the laws of nature ( or other intervening cause ) would simply forbid the traveler from doing anything that could later result in their time travel not occurring.

This is an interesting variation on just-in-time compilation, and it results in a much better advantage over an interpreter, since many instructions can be executed in native code without making intervening decisions on the ' direction ' register.

where A is the Hamaker coefficient, which is a constant (~ 10 < sup >− 19 </ sup > − 10 < sup >− 20 </ sup > J ) that depends on the material properties ( it can be positive or negative in sign depending on the intervening medium ), and z is the center-to-center distance ; i. e., the sum of R < sub > 1 </ sub >, R < sub > 2 </ sub >, and r ( the distance between the surfaces ):.

# Creatively use and respond to change: We can have a positive impact on inevitable change by carefully observing, and then intervening at the right time.

This can be calculated efficiently because of a special property of the rolling checksum: if the rolling checksum of bytes through is, the rolling checksum of bytes through can be computed from, byte, and byte without having to examine the intervening bytes.

According to Schumpeter ( 2003 ), the changes in this equilibrium state to document in economic theory can only be caused by intervening factors coming from the outside.

Statistical associations are not necessarily causal, and a variety of secondary variables and alternative explanations can be possibly intervening.

The orientation functions so well that the bees can find a food source with the help of the waggle dance even if there are hindrances they must detour around like an intervening mountain.

Conjugation is the overlap of one p-orbital with another across an intervening sigma bond ( in larger atoms d-orbitals can be involved ).

This definition has been challenged recently because new studies of oceanic crust by the Integrated Ocean Drilling Program and other research cruises have shown that in situ ocean crust can be quite variable, and that in places volcanic rocks sit directly on peridotite tectonite, with no intervening gabbros.

Soundproofing can reduce the transmission of unwanted direct sound waves from the source to an involuntary listener through the use of distance and intervening objects in the sound path.

Increased activity during intervening healthy years between the original infection and onset of PPS can amplify the symptoms.

The experimenter can manipulate the independent variables ; these independent variables ( e. g., stimuli provided ) in turn influence the intervening variables ( e. g., motor skill, appetite ).

However, there can be non-trivial " propagation " ( or tunneling amplitudes ) from to through an intervening manifold with ; this reflects the topology of.

As explanations of behavior, intervening variables can lead to an error in logic called “ circular reasoning .” To avoid circular reasoning, two or more operational definitions of the same internal state must be present, and they must be correlated.

They may also move or capture diagonally along the diagonal lines in either " palace ", provided there is an intervening piece in the centre ( i. e. it can only happen if the cannon is at a corner of the " palace ") They are powerful at the beginning of the game when " hurdles " are plentiful, but lose value rapidly with attrition.

Other histological features of gummas include an intervening zone containing epithelioid cells with indistinct borders and multinucleated giant cells, and a peripheral zone of fibroblasts and capillaries.

Tumor cells may form gland-like round or elongated structures that resemble the embryologic ependymal canal, with long, delicate processes extending into the lumen ; more frequently present are perivascular pseudorosettes in which tumor cells are arranged around vessels with an intervening zone consisting of thin ependymal processes directed toward the wall of the vessel.

Neighbouring plant cells are therefore separated by a pair of cell walls and the intervening lamella, forming an extracellular domain known as the apoplast.

Without so much as a grimace or a gesture to show that he had noticed ( although he later admitted that he had ) Palmer proceeded to sink his 25-footer, and his gallery sent its explosive vocalization rolling back along the intervening fairways in reply.

The greenhouse frog ( Eleutherodactylus planirostris ) lays eggs in small groups in the soil where they develop in about two weeks directly into juvenile frogs without an intervening larval stage.

In September 1862, the Confederate campaign in Maryland ended in defeat at the Battle of Antietam, which dissuaded the British from intervening.

The intervening 7th century was a period of genuine syncretism during which Christian symbolism and doctrine gradually grew in influence.

It is unclear where Dürer travelled in the intervening period, though it is likely that he went to Frankfurt and the Netherlands.

The intervening elements react differently at different frequencies of light as they whip in and out of view, causing Alioth to have very strange spectral lines that fluctuate over a period of 5. 1 days.

During the intervening period, bmobile has obtained a virtual stranglehold on the cellular telecommunications market in the British Virgin Islands by a combination of low prices and aggressive advertising, as well as significant investment in infrastructure and technology.

Note that, although rarely occurring, if a runner tags and advances from second base ( or, theoretically, from first base ) all the way to home and scores ( without an intervening error ) the batter is credited with a sacrifice fly.

Even though other clubs had taken part in the competition in the intervening decade, the team which got to this final was still the first English side to do so.

-- With great difficulty they accomplished their long journey on foot, traversing also the intervening seas ( maria ), where it was possible, by ship, and eventually arrived at the Swedish port called Birka.

Both of the latter are epithalamia, a form of laudatory or erotic wedding-poetry that Sappho had been famous for but that had gone out of fashion in the intervening centuries.

If one of the intervening states was a superpower, a civil war is extended a further 72 %; a conflict such as the Angolan Civil War, in which there is two-sided foreign intervention, including by a superpower ( actually, two superpowers in the case of Angola ), would be 538 % longer on average than a civil war without any international intervention.

Wells tells Lois that in truth the people of the future simply considered Lois to be blinded by love, and that this has made her story a compelling one throughout the intervening years.

Over the intervening period much trade had been lost overseas.

But for some 16 intervening centuries of ongoing anatomical study, CSF remains unmentioned in the literature, perhaps because of the prevailing autopsy technique, which involved cutting off the head, thereby removing evidence of the CSF before the brain was examined.

Chief of Staff Matthew Ridgway dissuaded the President from intervening by presenting a comprehensive estimate of the massive military deployment that would be necessary.

There are many other types of multi-effect distillation processes, including one referred to as simply multi-effect distillation ( MED ), in which multiple chambers, with intervening heat exchangers, are employed.

By 1854 the British wanted to resume relations with Dost Mohammad, whom they had essentially ignored in the intervening twelve years.

This support has continued to the present, with President Hosni Mubarak often intervening personally to promote peace negotiations.

Dark bands in the absorption spectrum are due to the atoms in an intervening medium between source and observer, absorbing certain frequencies of the light between emitter and detector / eye, then emitting them in all directions, so that a dark band appears to the detector, due to the radiation scattered out of the beam.

One of the most important requirements of experimental research designs is the necessity of eliminating the effects of spurious, intervening, and antecedent variables.

The field lines are the paths that a point positive charge would seek to make as it was forced to move within the field ; they are however an imaginary concept with no physical existence, and the field permeates all the intervening space between the lines.
