Given that neutral resonance structures are preferred overall, when a resonance structure absolutely must bear a negative charge somewhere,place it on the atom best able to stabilize that charge.Since, in essence, “basicity is the opposite of stability”, this is the same as saying, “put the...
The term resonance is used to describe the bonding pattern or characteristics that occurs in certain molecules or ions - basically various structures that can dscribe a single molecule. Resonance hybrids are formed by the combination of several particular structures. The bonding...
Formal charge is used to determine the most plausible Lewis structure, while resonance occurs when there are two equally stable structures resulting in electron delocalization. For example, in the case of NOCl, the structure O=N-Cl has formal charges of 0 on all atoms and is more stabl...
Engineers try to protect against bridge failures in two main ways. If we learn to see bridges as "living structures," constantly aging and being degraded by weather and the environment. it's easy to understand that they need regular maintenance, just like our homes and bodies. Periodic inspect...

Recently, we developed and validated a nuclear magnetic resonance (NMR) relaxation–dispersion (RD)18,19,20-based method to measure the hybridization kinetics in DNA and RNA duplexes21. Using this approach, we showed that m6A preferentially slows the apparent rate of RNA duplex annealing by ~5...
What adjectives best describe our brand’s personality? Example personality pillar: “Imaginative, high-quality, optimistic, courageous, casual, fun.”– LEGO Step 4: Clarify Your Brand Positioning Positioning refers to the niche your brand occupies in the competitive landscape. Reflect on: ...
Simulated molecular dynamics trajectories of proteins and nucleic acids are often compared with nuclear magnetic resonance (NMR) data for the purposes of assessing the quality of the force field used or, equally important, trying to interpret ambiguous experimental data. In particular, nuclear Overhauser...
provide non-destructive, high-resolution data of external and internal structures or even the movement of small molecules through a root system in the case of plants. X-ray computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography fall into this category [56]....
Describe some of the common structural features of the receptors to which signal molecules bind? What are the possible values of l for each of the following values of n? n = 1, 2, 3, 4 What is the point called on a graph of pH vs log \frac{A^-}{HA} \text{ when } A^- = ...
