In structural biology, resolution can be broken down into 4 groups: (1) sub-atomic, when information about the electron density is obtained and quantum effects can be studied, (2) atomic, individual atoms are visible and an accurate three-dimensional model can be constructed, (3) helical, secondary structure, such as alpha helices and beta sheets; RNA helices (in ribosomes), (4) domain, no ...
The first act is usually used for exposition, to establish the main characters, their relationships, and the world they live in.Later in the first act, a dynamic, on-screen incident occurs, known as the inciting incident, or catalyst, that confronts the main character (the protagonist), and whose attempts to deal with this incident lead to a second and more dramatic situation, known as the ...
3-dimensional multiple sequence alignment, produced on the 1D-3D Group Alignment Viewer, by RCSB Protein Data Bank. 3D visualization – A common, one-dimensional, representation of a protein sequence is a list of the amino acids that form it. However, 3-dimensional alignment displays the way sequences may match each other.
Chromatographic peak resolution is given by = + where t R is the retention time and w b is the peak width at baseline. The bigger the time-difference and/or the smaller the bandwidths, the better the resolution of the compounds. Here compound 1 elutes before compound 2.
Tinbergen's four questions, named after 20th century biologist Nikolaas Tinbergen, are complementary categories of explanations for animal behaviour. These are also commonly referred to as levels of analysis . [ 1 ]
Boris Karloff in James Whale's 1931 film Frankenstein, based on Mary Shelley's 1818 novel.The monster is created by an unorthodox biology experiment.. Biology appears in fiction, especially but not only in science fiction, both in the shape of real aspects of the science, used as themes or plot devices, and in the form of fictional elements, whether fictional extensions or applications of ...
Molecular biology – study of biology and biological functions at the molecular level, with some cross over from biochemistry. Structural biology – a branch of molecular biology, biochemistry, and biophysics concerned with the molecular structure of biological macromolecules. Health sciences and human biology – biology of humans.
"The Three Questions" is a 1903 short story by Russian author Leo Tolstoy as part of the collection What Men Live By, and Other Tales. The story takes the form of a parable , and it concerns a king who wants to find the answers to what he considers the three most important questions in life.
