    Unreferenced stub auto yes date December 2009 A Theta structure is an intermediate structure formed during the DNA replication replication of a circular DNA molecule prokaryote DNA , two replication fork s can proceed independently around the DNA ring and when viewed from above it resembles the Greek letter theta . Originally discovered by John Cairns biochemist John Cairns , it led to the understanding that in this case bidirectional DNA replication could take place. Proof of the bidirectional nature came from providing replicating cells with a pulse of tritium Analytical chemistry tritiated thymidine , quenching rapidly and then autoradiograph ing. Results showed that the radioactive thymidine was incorporated into both forks of the theta structure, not just one, indicating synthesis at both forks, in opposite directions around the loop.

  1. Theta criterion

    In syntax , the theta criterion in its original form states that in a grammatical sentence, every theta role that a verb can assign must be realized by some verb argument argument , and each argument may bear only a single theta role. ref cite book title Lectures on Government and Binding The Pisa Lectures author Chomsky, Noam year 1981 1993 publisher Mouton de Gruyter See p. 36 ref So, for instance, for the verb send , which is associated with the theta roles of Agent, Goal and Theme, a well formed sentence might look like this Robert sent Mary a package. Here, the three theta roles are assigned to Robert , Mary and a package , respectively. The sentence would have been malformed if any of these arguments had been absent. Apparent violations It is often noted that sometimes arguments of the verb are not overtly present, and that sometimes the verb may take more arguments than specified in the lexicon Gladius Maximus died the death befitting a Roman soldier . John ate . Going to the store, be back later Linguists often explain sentences 2 and 3, where the verbs seem to be missing arguments, by positing a silent pronoun pro that occupies the phonologically empty argument positions. This can be justified by noting that one cannot get the meaning from sentence 2 that John ate something inedible, such as a rock, and that in sentence 3 there is a clear implied first person subject. In sentence 1, however, there is no clear theta position that the death befitting a Roman soldier is occupying it is unclear what licenses this cognate object , producing a pseudo transitive use of the verb died . One plausible explication is the interpretation of the verb die in this phrase as synonym of suffer , undergo or be impaired thus, the sentence may be interpreted as Gladius Maximus suffered the death befitting a Roman soldier . And then, the arguments are complete. References references Category Thematic roles ling stub nl Th ta criterium ...   more details

  1. Theta characteristic

    In mathematics , a theta characteristic of a non singular algebraic curve C is a divisor class such that 2 is the canonical class , In terms of holomorphic line bundle s L on a connected compact Riemann surface , it is therefore L such that L sup 2 sup is the canonical bundle , here also equivalently the holomorphic cotangent bundle . In terms of algebraic geometry , the equivalent definition is as an invertible sheaf , which squares to the sheaf of differentials of the first kind . Theta characteristics were introduced by harvs txt last Rosenhain authorlink Johann Georg Rosenhain year 1851 History and genus 1 The importance of this concept was realised first in the analytic theory of theta function s, and geometrically in the theory of bitangent s. In the analytic theory, there are four fundamental theta functions in the theory of Jacobian elliptic function s. Their labels are in effect the theta characteristics of an elliptic curve . For that case, the canonical class is trivial zero in the divisor class group and so the theta characteristics of an elliptic curve E over the complex ...
