Hybridization of Atomic Orbitals I

2020
The mathematical expression known as the wave function, ψ, contains information about each orbital and the wavelike properties of electrons in an isolated atom. When atoms are bound together in a molecule, the wave functions combine to produce new mathematical descriptions that have different shapes. This process of combining the wave functions for atomic orbitals is called hybridization and is mathematically accomplished by the linear combination of atomic orbitals. The new orbitals that...

Whole-Mount In Situ Hybridization

Whole-mount in situ hybridization (WMISH) is a common technique used for visualizing the location of expressed RNAs in embryos. In this process, synthetically produced RNA probes are first complementarily bound, or "hybridized," to the transcripts of target genes. Immunohistochemistry or fluorescence is then used to detect these RNA hybrids, revealing spatial and temporal patterns of gene expression. Unlike traditional in situ hybridization techniques, which require thin tissue sections whose...

sp3d and sp3d 2 Hybridization To describe the five bonding orbitals in a trigonal bipyramidal arrangement, we must use five of the valence shell atomic orbitals (the s orbital, the three p orbitals, and one of the d orbitals), which gives five sp3d hybrid orbitals. With an octahedral arrangement of six hybrid orbitals, we must use six valence shell atomic orbitals (the s orbital, the three p orbitals, and two of the d orbitals in its valence shell), which gives six sp3d 2 hybrid orbitals.

We have directly incorporated a stilbene-based organic dye into a cobaloxime core to generate a photosensitizer-catalyst dyad for photocatalytic H2 production. We have also developed a simple experimental setup for evaluating the light-driven H2 production by photocatalytic assemblies.

This video demonstrates 2-color whole mount in situ hybridization, a method by which the spatial and temporal expression pattern of 2 different genes can be visualized in young chick embryos. This method was originally introduced by David Wilkinson, Domingos Henrique, Phil Ingham and David Ish -Horowicz.
FAQs
Temperature and salt concentration strongly influence the stability and selectivity of nucleic acid binding. Lower stringency conditions, produced by comparatively less restrictive settings, allow strands with more sequence mismatches to associate. Higher stringency favors highly complementary targets. Adjusting these variables helps researchers reduce nonspecific binding while retaining sufficient interaction for detection.
pH and denaturants alter the molecular environment in which complementary DNA or RNA strands interact. Their effects contribute to the overall stringency of an assay, alongside temperature and salt concentration. Researchers consider these variables when optimizing binding so that the probe recognizes the intended sequence without losing the signal needed for reliable molecular detection.
Probe length is an important Hybridization Conditions variable because it influences how researchers balance binding strength with sequence discrimination. Together with temperature, salt concentration, and other parameters, probe length affects whether mismatched targets remain associated. Selecting conditions appropriate to the probe helps distinguish highly complementary sequences from related sequences that share only partial similarity.
Optimization begins by matching the experimental settings to the desired balance between binding and specificity. Researchers adjust temperature, salt concentration, pH, denaturants, and probe length, then evaluate whether the resulting signal supports dependable target detection. Conditions that are too permissive may allow mismatches, whereas overly stringent settings can favor specificity at the expense of detectable binding.
Labeled DNA or RNA probes are used in several assays that require sequence-specific detection. Southern blotting can detect DNA sequences, while Northern blotting examines RNA-related targets. Fluorescence in situ hybridization supports sequence localization, and microarrays enable comparison of specific nucleic acid sequences. In each case, controlled conditions help determine which targets produce interpretable signals.
Optimized hybridization can support three broad outcomes: detecting a specific nucleic acid sequence, locating that sequence within a biological sample, or comparing sequence-related signals. The appropriate interpretation depends on the assay, such as blotting, fluorescence in situ hybridization, or a microarray. Reliable conditions improve confidence that observed signals reflect intended complementarity rather than tolerated mismatches.
