Repression
Repression may refer to: * Memory inhibition, the ability to filter irrelevant memories from attempts to recall * Political repression, the oppression or persecution of an individual or group for political reasons * Psychological repression, the psychological act of excluding desires and impulses from one's consciousness * Social repression, the socially supported mistreatment and exploitation of a group of individuals * Genetic repression, the down-regulation of gene transcription by the action of repressor In molecular genetics, a repressor is a DNA- or RNA-binding protein that inhibits the expression of one or more genes by binding to the operator or associated silencers. A DNA-binding repressor blocks the attachment of RNA polymerase to the ... proteins binding to a promoter * "Repression" (''Star Trek: Voyager''), an episode of the science fiction television series ''Star Trek: Voyager'', the fourth episode of the seventh (and final) season of the series {{disamb ...

Psychological Repression
Repression is a key concept of psychoanalysis, where it is understood as a defence mechanism that "ensures that what is unacceptable to the conscious mind, and would if recalled arouse anxiety, is prevented from entering into it." According to psychoanalytic theory, repression plays a major role in many mental illnesses, and in the psyche of the average person.Laplanche pp. 390, 392 There has been debate as to whether (or how often) memory repression really occurs and mainstream psychology holds that true memory repression occurs infrequently. American psychologists began to attempt to study repression in the experimental laboratory around 1930. However, psychoanalysts were at first uninterested in attempts to study repression in laboratory settings, and later came to reject them. Most psychoanalysts concluded that such attempts misrepresented the psychoanalytic concept of repression.

Political Repression
Political repression is the act of a state entity controlling a citizenry by force for political reasons, particularly for the purpose of restricting or preventing the citizenry's ability to take part in the political life of a society, thereby reducing their standing among their fellow citizens. It is often manifested through policies such as human rights violations, surveillance abuse, police brutality, imprisonment, involuntary settlement, stripping of citizen's rights, lustration, and violent action or terror such as the murder, summary executions, torture, forced disappearance, and other extrajudicial punishment of political activists, dissidents, or general population. Political repression can also be reinforced by means outside of written policy, such as by public and private media ownership and by self-censorship within the public. Where political repression is sanctioned and organised by the state, it may constitute state terrorism, genocide, politicide or cr ...

Repressor
In molecular genetics, a repressor is a DNA- or RNA-binding protein that inhibits the expression of one or more genes by binding to the operator or associated silencers. A DNA-binding repressor blocks the attachment of RNA polymerase to the promoter, thus preventing transcription of the genes into messenger RNA. An RNA-binding repressor binds to the mRNA and prevents translation of the mRNA into protein. This blocking or reducing of expression is called repression. Function If an inducer, a molecule that initiates the gene expression, is present, then it can interact with the repressor protein and detach it from the operator. RNA polymerase then can transcribe the message (expressing the gene). A co-repressor is a molecule that can bind to the repressor and make it bind to the operator tightly, which decreases transcription. A repressor that binds with a co-repressor is termed an ''aporepressor'' or ''inactive repressor''. One type of aporepressor is the trp repressor, a ...

Memory Inhibition
Memory is the faculty of the mind by which data or information is encoded, stored, and retrieved when needed. It is the retention of information over time for the purpose of influencing future action. If past events could not be remembered, it would be impossible for language, relationships, or personal identity to develop. Memory loss is usually described as forgetfulness or amnesia. Memory is often understood as an informational processing system with explicit and implicit functioning that is made up of a sensory processor, short-term (or working) memory, and long-term memory. This can be related to the neuron. The sensory processor allows information from the outside world to be sensed in the form of chemical and physical stimuli and attended to various levels of focus and intent. Working memory serves as an encoding and retrieval processor. Information in the form of stimuli is encoded in accordance with explicit or implicit functions by the working memory processo ...

Social Repression
Oppression is malicious or unjust treatment or exercise of power, often under the guise of governmental authority or cultural opprobrium. Oppression may be overt or covert, depending on how it is practiced. Oppression refers to discrimination when the injustice does not target and may not directly afflict everyone in society but instead targets or disproportionately impacts specific groups of people. No universally accepted model or terminology has yet emerged to describe oppression in its entirety, although some scholars cite evidence of different types of oppression, such as social oppression, cultural, political, religious/belief, institutional oppression, and economic oppression. The Universal Declaration of Human Rights offers a benchmark from which to assess both individual and structural models of oppression. The concept, popularized in Marx and Engels' Communist Manifesto of 1848, is often used to justify state persecution. Authoritarian oppression The word ''oppress ...
