This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
CARDs were originally characterized based on their involvement in the regulation of caspase activation and apoptosis. [2] The basic six-helix structure of the domain appears to be conserved as far back as the ced-3 and ced-4 genes in C. elegans, the organism in which several components of the apoptotic machinery were first characterized.
It is helpful to be able to understand the source of scientific names. Although the Latin names do not always correspond to the current English common names, they are often related, and if their meanings are understood, they are easier to recall. The binomial name often reflects limited knowledge or hearsay about a species at the time it was named.
Biology is the scientific study of life. [ 1 ] [ 2 ] [ 3 ] It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. [ 1 ] [ 2 ] [ 3 ] For instance, all organisms are composed of at least one cell that processes hereditary information encoded in genes , which can be transmitted ...
A simple smiley. This is a list of emoticons or textual portrayals of a writer's moods or facial expressions in the form of icons.Originally, these icons consisted of ASCII art, and later, Shift JIS art and Unicode art.
Carotenoids are red, orange, or yellow tetraterpenoids. During the process of photosynthesis, they have functions in light-harvesting (as accessory pigments ), in photoprotection (energy dissipation via non-photochemical quenching as well as singlet oxygen scavenging for prevention of photooxidative damage), and also serve as protein structural ...
The CARD-CC protein family is defined by an evolutionary conserved "caspase activation and recruitment domain" and a coiled-coil (CC) domain. [1] [2] Coiled-coils (CC) act as oligomerization domains for many proteins such as structural and motor proteins, and transcription factors.
A phenakistoscope (described in the display as a "Phantasmascope") with cards. On display in Bedford Museum, England. The phénakistiscope usually comes in the form of a spinning cardboard disc attached vertically to a handle. Arrayed radially around the disc's center is a series of pictures showing sequential phases of the animation.
