The goal is ultimately to understand how the movement of individual limbs relates to the overall movement of an animal within its environment. Below highlights the key kinematic parameters used to quantify body and limb movement for different modes of animal locomotion.
Many manifestations of the cage effect exist. [8] In free radical polymerization, radicals formed from the decomposition of an initiator molecule are surrounded by a cage consisting of solvent and/or monomer molecules. [6] Within the cage, the free radicals undergo many collisions leading to their recombination or mutual deactivation.
amoeboid movement, a crawling-like movement, which also makes swimming possible [17] [18] filopodia , enabling movement of the axonal growth cone [ 19 ] flagellar motility , a swimming-like motion (observed for example in spermatozoa , propelled by the regular beat of their flagellum , or the E. coli bacterium, which swims by rotating a helical ...
In developmental biology, animal embryonic development, also known as animal embryogenesis, is the developmental stage of an animal embryo. Embryonic development starts with the fertilization of an egg cell (ovum) by a sperm cell (spermatozoon). [1] Once fertilized, the ovum becomes a single diploid cell known as a zygote.
An approach to model morphogenesis in computer science or mathematics can be traced to Alan Turing's 1952 paper, "The chemical basis of morphogenesis", [30] a model now known as the Turing pattern. Another famous model is the so-called French flag model , developed in the sixties.
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 movement of the cytoskeletal microfilaments causes a mechanical force which travels to the adhesion complexes on the substrate to move the cell forward. [15] Motor and regulatory proteins that convert intracellular motion into mechanical forces like traction force have been discovered to be a conserved class of intracellular motors in ...
CAGE tags tend to start with an extra guanine (G) that is not encoded in the genome, which is attributed to the template-free 5′-extension during the first-strand cDNA synthesis [2] or reverse-transcription of the cap itself. [3] When not corrected, this can induce erroneous mapping of CAGE tags, for instance to nontranscribed pseudogenes. [2]
