4 dni temu · In both local and long-distance signaling, only specific target cells recognize and respond to a given signaling molecule. Local signaling includes Paracrine signaling (A secreting cell acts on nearby target cells by discharging molecules of a local regulator into the extracellular fluid.) and Synaptic Signaling (A nerve cell releases ...
3 dni temu · A genetic map (also called a linkage map) shows the relative location of genetic markers (reflecting sites of genomic variants) on a chromosome. A genetic map is based on the concept of genetic linkage: the closer two markers are to each other on a chromosome, the greater the probability that they will be inherited together.
6 dni temu · A physical map, as related to genomics, is a graphical representation of physical locations of landmarks or markers (such as genes, variants and other DNA sequences of interest) within a chromosome or genome. A complete genome sequence is one type of physical map.

19 godz. temu · Hubble's law, also known as the Hubble–Lemaître law, is the observation in physical cosmology that galaxies are moving away from Earth at speeds proportional to their distance. In other words, the farther they are, the faster they are moving away from Earth. The velocity of the galaxies has been determined by their redshift, a shift of the light they emit toward the red end of the visible ...
3 dni temu · A marker (largely synonymous with the word “landmark” and often referred to as a genomic marker or a genetic marker) is a DNA sequence, typically with a known location in a genome. Markers can reflect random sequences, genomic variants or genes.
