BioArt. BioArt is an art practice where artists work with biology, live tissues, bacteria, living organisms, and life processes. Using scientific processes and practices such as biology and life science practices, microscopy, and biotechnology (including technologies such as genetic engineering, tissue culture, and cloning) the artworks are ...
Cell Painting. The Cell Painting assay is a high-content, high-throughput imaging technique used to capture a wide array of cellular phenotypes in response to diverse perturbations. [1] These phenotypes, often termed "morphological profiles", can be used to understand various biological phenomena, including cellular responses to genetic changes ...
The pin-point method (or point-intercept method) is used for non-destructive measurements of plant cover and plant biomass. [1] [2] In a pin-point analysis, a frame (or a transect) with a fixed grid pattern is placed above the vegetation. A pin is inserted vertically through one of the grid points into the vegetation and will typically touch a ...
Coalescent theory. Coalescent theory is a model of how alleles sampled from a population may have originated from a common ancestor. In the simplest case, coalescent theory assumes no recombination, no natural selection, and no gene flow or population structure, meaning that each variant is equally likely to have been passed from one generation ...
Isoelectric focusing. Scheme of isoelectric focusing with immobilized pH gradient (IPG) gels. Isoelectric focusing ( IEF ), also known as electrofocusing, is a technique for separating different molecules by differences in their isoelectric point (pI). [ 1][ 2] It is a type of zone electrophoresis usually performed on proteins in a gel that ...
The left fixed point is always unstable, and the right one stable. Figure 5. Ideal transcritical bifurcation phase portraits. Fixed points are marked on the x-axis, each trajectory in a different color. The direction of the arrows indicates which direction they move as r increases. The red point is unstable, and the blue point is unstable.
Microtechnique is an aggregate of methods used to prepare micro-objects for studying. [1] It is currently being employed in many fields in life science. Two well-known branches of microtechnique are botanical (plant) microtechnique and zoological (animal) microtechnique. With respect to both plant microtechnique and animal microtechnique, four ...
Steps of the cell cycle. The restriction point occurs between the G 1 and S phases of interphase.. The restriction point (R), also known as the Start or G 1 /S checkpoint, is a cell cycle checkpoint in the G 1 phase of the animal cell cycle at which the cell becomes "committed" to the cell cycle, and after which extracellular signals are no longer required to stimulate proliferation.
