First, I drew the correct Lewis structure which is a graphical representation that shows the pairs of electrons linking the atoms of a molecule and the pairs of solitary electrons which may exist. To predict molecular geometry I used the VSEPR model, which is based on the number of elect...
Important for this post is that both theories are approximations for the wave function of a molecule, hence they do not describe bonding beyond the stationary point they are applied to, and they operate within the clamped nuclei (Born-Oppenheimer) approximation. In MO theory it is common to ex...
The simultaneous detection of CXCR4 and markers for the mesodermal and neural crest cells in multiple labelling allowed us to compare complex gene expression patterns and it could be easily used for a wide range of gene expression pattern analyses of other chicken embryonic tissues. All steps of ...
the white light is an illusion as everything is a part of us and we are a part of everything. The nature of reality is holographic. It is consciousness, awareness. Consciousness manifests what we perceive to be reality.
Lewis structures provide you with a simple way to draw out an organic molecule showing every atom, bond, and lone electron pair. While not ideal for demonstrating bond angle and molecular geometry, it's a great way to begin your understanding of molecules and bonding in organic chemistry. ...
How can we “find” resonance forms for a given molecule? It’s possible to do it through trial-and-error, but one surefire way is to do so is to apply the curved arrow formalism, which is a way of depicting the “movement” of electrons. ...
Non-coding mRNA structures that sense the environmental status of a cell by directly binding to small molecule ligands, such as a metabolite or an ion. This interaction changes the RNA conformation and controls gene expression through alternative splicing, transcription or translation. Peptidyl transfera...
Transcriptional bursting has been linked to the stochastic positioning of nucleosomes. However, how bursting is regulated by the remodeling of promoter nucleosomes is unknown. Here, we use single-molecule live-cell imaging of GAL10 transcription in Saccharomyces cerevisiae to measure how bursting change...
Down syndrome(trisomy 21) can be diagnosed almost as soon as a baby is born, based on distinctive physical characteristics that prompt immediate testing. Signs of Down syndrome can be detected during a pregnancy ultrasound, too. But, in order to confirm the diagnosis, other prenatal tests, incl...
of Watson–Crick pairing with uridine, the model assumes that hybridization only proceeds via annealing of the single-strand containing the minorantiisomer (ssRNAanti) through a CS-type pathway27,28(Fig.2a). The apparentkonwould then be reduced relative to the unmethylated RNA because the ...
