Into the texture of this tapestry of history and human drama Henrietta, as every artist delights to do, wove strands of her own intuitive insights into human nature and -- especially in the remarkable story of the attraction and conflict between two so disparate and fervent characters as this pair -- into the relations of men and women: `` In their relations, she was the giver and he the receiver, nay the demander.

This was some freak, two strands of adhesive tape across his nose, like ugly roots from the mass of gauze, suddenly moist over his cheekbones.

The virus particle consists of 10 strands of double-stranded RNA surrounded by two protein shells.

In molecular biology and genetics, the linking between two nitrogenous bases on opposite complementary DNA or certain types of RNA strands that are connected via hydrogen bonds is called a base pair ( often abbreviated bp ).

Paired DNA and RNA molecules are comparatively stable at room temperature but the two nucleotide strands will separate above a melting point that is determined by the length of the molecules, the extent of mispairing ( if any ), and the GC content.

Beta sheets consist of beta strands connected laterally by at least two or three backbone hydrogen bonds, forming a generally twisted, pleated sheet.

b ) Edge-on view of the central two β strands in a, showing the righthanded twist and the pleat of Cαs and sidechains that alternately stick out in opposite directions from the sheet.

In the most common usage, β strand refers to a single continuous stretch of amino acids adopting an extended conformation and involved in backbone hydrogen bonds to at least one other strand ; by contrast, a β sheet refers to an assembly of at least two such β strands that are hydrogen-bonded ( or H-bonded ) to each other.

Unduplicated chromosomes are single linear strands, whereas duplicated chromosomes contain two identical copies ( called chromatids ) joined by a centromere.

These two strands run in opposite directions to each other and are therefore anti-parallel, one backbone being 3 ' ( three prime ) and the other 5 ' ( five prime ).

These two long strands entwine like vines, in the shape of a double helix.

The bases lie horizontally between the two spiraling strands.

The two strands of DNA in a double helix can therefore be pulled apart like a zipper, either by a mechanical force or high temperature.

The denaturation of nucleic acids such as DNA due to high temperatures is the separation of a double strand into two single strands, which occurs when the hydrogen bonds between the strands are broken.

Adenine pairs with thymine ( two hydrogen bonds ), and cytosine pairs with guanine ( three hydrogen bonds ) because a purine must pair with a pyrimidine: a pyrimidine cannot pair with another pyrimidine because the strands would be very close to each other ; in a purine pair, the strands would be too far apart and the structure would be unstable.

This process is initiated at particular points in the DNA, known as " origins ", which are targeted by proteins that separate the two strands and initiate DNA synthesis.

Origins tend to be " AT-rich " ( rich in adenine and thymine bases ) to assist this process, because A-T base pairs have two hydrogen bonds ( rather than the three formed in a C-G pair )— in general, strands rich in these nucleotides are easier to separate since less energy is required to break relatively fewer hydrogen bonds.

In these once the two strands are separated, RNA primers are created on the template strands.

All these proteins share a catalytic mechanism of di-metal-ion-mediated nucleotide transfer, whereby two acidic residues located at the end of the first strand and between the second and third strands of the RRM-like unit respectively, chelate two divalent cations.

As DNA synthesis continues, the original DNA strands continue to unwind on each side of the bubble, forming a replication fork with two prongs.

After the discovery of the hydrogen bonded A: T and C: G pairs, Watson and Crick soon had their anti-parallel, double helical model of DNA, with the hydrogen bonds at the core of the helix providing a way to " unzip " the two complementary strands for easy replication: the last key requirement for a likely model of the genetic molecule.

The public interest is so dominant in such an issue that I cannot be so presumptuous as to attempt to settle it by an administrative order based upon conclusions reached in a summary action in one or two Superior Courts in the State.

The photoelectrons emitted from a circular segment of the cathode sphere are focused by the positive lens action of the two concentric spheres, pass through the ( negative ) lens formed by the anode aperture, and impinge upon the cathodoluminescent viewing screen.

`` When in doubt as to two courses of action, a general should choose the bolder ''.

Military action was heavily influenced by the Russian military, which inspired and manipulated the rivalry between the two neighbouring nations in order to keep both under control.

The most important of these was the principle that came to be called Ampère ’ s law, which states that the mutual action of two lengths of current-carrying wire is proportional to their lengths and to the intensities of their currents.

Ajax at first gets the better of the encounter, wounding Hector with his spear and knocking him down with a large stone, but Hector fights on until the heralds, acting at the direction of Zeus, call a draw: the action ends without a winner and with the two combatants exchanging gifts, Ajax giving Hector a purple sash and Hector giving Ajax a sharp sword.

A threat of invasion by Henry in 1243 for a time interrupted the friendly relations between the two countries ; but the prompt action of Alexander in anticipating his attack, and the disinclination of the English barons for war, compelled him to make peace next year at Newcastle.

Hence, there are two different conceptions of art in aesthetics: art as knowledge or art as action, but aesthetics is neither epistemology nor ethics.

Albrecht Altdorfer's depiction of the moment in 333 BC when Alexander the Great routed Darius III for supremacy in Asia Minor is vast in ambition, sweeping in scope, vivid in imagery, rich in symbols, and obviously heroic — the Iliad of painting, as literary critic Friedrich Schlegel suggested In the painting, a swarming cast of thousands of soldiers surround the central action: Alexander on his white steed, leading two rows of charging cavalrymen, dashes after a fleeing Darius, who looks anxiously over his shoulder from a chariot.

Slicing and using a shortened hitting action are the two main technical devices that facilitate deception.

Count Horn directed the Prince of Holstein-Beck to take the village, but his two Dutch brigades were cut down by the French and Irish troops, capturing and badly wounding the Prince during the action.

At 13: 00 the batteries went into action ; a little later two Allied columns set out from the extremities of their line and attacked the flanks of the Franco-Bavarian army.

However the loss of Culloden, the relative sizes of Orient and Leander and the participation in the action by two of the French frigates and several smaller vessels, as well as the theoretical strength of the French position, leads most historians to the conclusion that the French were marginally more powerful.

In particular, the successful entrapment of Graham Riddick and David Tredinnick in the " cash for questions " scandal, the contemporaneous misconduct as ministers by Neil Hamilton ( who lost a consequent libel action against The Guardian ), Tim Smith, and the convictions of former Cabinet member Jonathan Aitken and former party deputy chairman Jeffrey Archer for perjury in two separate cases leading to custodial sentences damaged the Conservatives ' public reputation.

But, before the 1989 Abbey National Building Society demutualisation, the Courts found against the two year rule after legal action brought by Abbey National itself in order to circumvent the intent of the legislators.

The latter two don't make sense, so " looks " in this case is being used as an action verb.

The most common use of cutaway shots in dramatic films are to adjust the pace of the main action, to conceal the deletion of some unwanted part of the main shot, or to allow the joining of parts of two versions of that shot.

Following the classical dynamics of Newton and Euler, the motion of a material body is produced by the action of externally applied forces which are assumed to be of two kinds: surface forces and body forces.

The mode of action of chymotrypsin explains this as hydrolysis takes place in two steps.

At the end of the 1980s, the word " cartoon " was shortened, and the word " toon " came into usage with the live action / animated feature Who Framed Roger Rabbit ( 1988 ), followed two years later by the TV series Tiny Toon Adventures ( 1990 ).

Under the proposals the court will be able to decide whether to allow an action brought by an association on behalf of consumers ( which must comprise at least two individuals ) for goods purchased under a standard contract.

At this time there were two customary means of selecting a leader: having a hereditary leader for general purposes, and choosing someone with good qualities in times of crisis or opportunities for action.

When cells enter mitosis, the sister chromatids ( which represent the two copies of each chromosomal DNA molecule resulting from DNA replication earlier in the cell cycle and packaged by histones and other proteins into chromatin ) are linked all along their length by the action of the cohesin complex.

Clark wears his Superman costume underneath his street clothes, allowing easy changes between the two personae — and the dramatic gesture of ripping open his shirt to reveal the familiar " S " emblem when called into action.

Perhaps his two most influential ideas are the concepts of the public sphere and communicative action ; the latter arriving partly as a reaction to new post-structural or so-called " post-modern " challenges to the discourse of modernity.
