Directionality, in molecular biology and biochemistry, is the end-to-end chemical orientation of a single strand of nucleic acid. In a single strand of DNA or RNA, the chemical convention of naming carbon atoms in the nucleotide pentose-sugar-ring means that there will be a 5′ end (usually pronounced "five-prime … See more The 5′-end (pronounced "five prime end") designates the end of the DNA or RNA strand that has the fifth carbon in the sugar-ring of the deoxyribose or ribose at its terminus. A phosphate group attached to the 5′-end permits See more • Sense (molecular biology) See more • Harvey Lodish; Arnold Berk; Paul Matsudaira; Chris A. Kaiser (2004). Molecular Cell Biology (5th ed.).

See more The 3′-end (three prime end) of a strand is so named due to it terminating at the hydroxyl group of the third carbon in the sugar-ring, and is known as the tail end.

The 5′ is upstream; the 3′ is downstream. DNA and RNA are synthesized in the 5′-to-3′ direction.

WebThe central dogma concerns the flow of biological information: DNA is a self-replicating molecule containing genetic information that can be transcribed into an RNA message that can be translated into a polypeptide (protein). f From DNA to Protein Figure 6-21. Summary of the steps leading from gene to protein in eucaryotes and bacteria. WebApr 12, 2024 · We propose a perfectly vertical coupling scheme based on metasurface deflectors (meta-deflectors) and grating couplers (GCs). An approach for optimizing the GCs based on the Gaussian-fitting using the genetic algorithm is proposed. An meta-deflector based on amorphous silicon (a-Si) pillars is designed to the optimal coupling angle of the … thicker skin synonym

WebJan 31, 2024 · Current seismic analysis contemplates the simultaneous use of the orthogonal components of an earthquake in order to determine the structural stresses closer to reality. This has led to these components being combined considering a fraction of them, as applying them completely would lead to excessively conservative results. However, … WebThe directionality of θ − ω distribution can be also observed and that is more evident as ρ increases. For orthotropic materials, θ − ω shows point symmetric behavior with respect to the hole center where positive and negative θ − ω can be both observed, but the value of θ − ω is close to 0.
