Regulation of Expression Occurs at Multiple Steps

Regulation of Expression Occurs at Multiple Steps

Gene expression can be regulated at almost every step from gene to protein. Transcription is the step that is most commonly regulated. This involves the binding of proteins to short regulatory sequences on the DNA. This association can either promote or inhibit the transcription of a gene associated with the respective sequence.
Transcription results in the generation of precursor (pre-mRNA) that consists of both exons and introns, which needs further processing before being translated to a...

Colors and Magnetism

Colors and Magnetism

Color in Coordination Complexes
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...

Color Vision

Color Vision

Color perception begins in the retina, the light-sensitive layer at the back of the eye. Two main theories explain how colors are seen: the trichromatic theory and the opponent-process theory. The trichromatic theory, proposed by Thomas Young in 1802 and extended by Hermann von Helmholtz in 1852, suggests that color vision is based on three types of cone receptors in the retina. These cones are sensitive to different but overlapping ranges of wavelengths corresponding to red, blue, and green.

The Equilibrium Binding Constant and Binding Strength

The Equilibrium Binding Constant and Binding Strength

The equilibrium binding constant (Kb) quantifies the strength of a protein-ligand interaction. Kb can be calculated as follows when the reaction is at equilibrium:

Ligand Binding Sites

Ligand Binding Sites

Proteins are dynamic macromolecules that carry out a wide variety of essential processes; however, the activities of most proteins depend on their interactions with other molecules or ions, known as ligands.
Protein-ligand interactions are quite specific; even though numerous potential ligands surround a cellular protein at any given time, only a particular ligand can bind to that protein. Moreover, a ligand binds only to a dedicated area on the surface of the protein, known as the...

Summary

Feature binding, the process of combining sensory information, can occur unconsciously. This suggests that unconscious feature binding does not require visual consciousness for its formation.

Area of Science:

Cognitive Neuroscience
Psychology of Vision

Background:

The relationship between feature binding and visual consciousness is a long-standing debate.
Evidence suggests feature binding and visual consciousness may be separable.

Purpose of the Study:

To investigate whether feature binding can occur independently of visual consciousness.
To determine if unconscious processing of combined features influences subsequent perception.

Main Methods:

Manipulated the visibility of priming stimuli (color-motion features).
Measured the impact of these stimuli on the reporting of cued target direction.
Utilized a priming paradigm to assess unconscious feature binding.

Main Results:

A priming effect was observed even when priming stimuli were invisible.
This indicates that color-motion features can bind unconsciously.
Unconscious feature binding occurred without conscious awareness of the prime.

Conclusions:

Feature binding and visual consciousness are separable psychological processes.
Feature binding is not sufficient for establishing visual awareness.
Unconscious feature binding can influence conscious perception.
