Kinesin A kinesin is a protein belonging to a class of motor proteins found in eukaryotic cells. Kinesins move along microtubule (MT) filaments, and are powered by the hydrolysis of adenosine triphosphate (ATP) (thus kinesins are ATPases).The active movement of kinesins supports several cellular functions including mitosis, meiosis and transport of cellular cargo, such as in axonal transport.he founding member of this superfamily, kinesin-1, was isolated as a heterotetrameric fast axonal organelle transport motor consisting of 2 identical motor subunits (KHC) and 2 light chains (KLC) via microtubule affinity purification from neuronal cell extracts.

Cohesin Cohesin is a protein complex that regulates the separation of sister chromatids during cell division, either mitosis or meiosis. Cohesins hold sister chromatids together after DNA replication until anaphase when removal of cohesin leads to separation of sister chromatids.

- Crocin. Crocin is a natural carotenoid chemical compound that is found in the flowers crocus and gardenia. It is the diester formed from the disaccharide gentiobiose and the dicarboxylic acid crocetin.It has a deep red color and forms crystals with a melting point of 186 °C.When dissolved in water, it forms an orange solution. Crocin is the chemical ingredient primarily responsible for the color of saffron.t is the diester formed from the disaccharide gentiobiose and the dicarboxylic acid crocetin.

What is Secretin? Secretin is a hormone produced in the duodenum which plays an important role in the digestive process and also appears to be involved in osmoregulation, the process the body uses to keep the internal balance of salt and fluids stable.

Ricin Ricin (/ˈraɪsɪn/ REYE-sin) is a highly toxic, naturally occurring lectin (a carbohydrate-binding protein) produced in the seeds of the castor oil plant, Ricinus communis. A dose of purified ricin powder the size of a few grains of table salt can kill an adult human. The median lethal dose (LD50) of ricin is around 22 micrograms per kilogram of body weight if the exposure is from injection or inhalation (1.78 milligram for an average adult).

Kinesin A different type of motor protein known as dyneins, move towards the minus end of the microtubule. Thus they transport cargo from the periphery of the cell towards the centre, for example from the terminal boutons of a neuronal axon to the cell body (soma). This is known as retrograde transport.Cin8, a member of the Kinesin-5 family, has the novel ability to switch directionality.hus they transport cargo from the periphery of the cell towards the centre, for example from the terminal boutons of a neuronal axon to the cell body (soma).

Kinesin-5, a mitotic microtubule-associated motor protein, modulates neuronal migration Kinesin-5 (also called Eg5 or kif11) is a homotetrameric motor protein that functions by modulating microtubule (MT)–MT interactions. In the case of mitosis, kinesin-5 slows the rate of separation of the half-spindles.

Definitions &Translations Kinesiology, also known as human kinetics, is the scientific study of human movement. Kinesiology addresses physiological, mechanical, and psychological mechanisms. Applications of kinesiology to human health include biomechanics and orthopedics; strength and conditioning; sport psychology; methods of rehabilitation, such as physical and occupational therapy; and sport and exercise.

Kinana English Voice. Kinana (キナナ Kinana) is a member of the Fairy Tail Guild and the former pet of Oración Seis member, Erik. Unlike most other members of Fairy Tail, she initially joined the guild as an employee, rather than as a Mage. After Fairy Tail's disbandment she is finally able to use magic, rejoining the guild as a Mage.

Motor protein Kinesins are a group of related motor proteins that use a microtubule track in antegrade movement. They are vital to the movement of chromosomes during mitosis and are also responsible for shuttling mitochondria, Golgi bodies, and vesicles within eukaryotic cells.

Star Stellar kinematics is the study of the movement of stars without needing to understand how they acquired their motion. This differs from stellar dynamics, which takes into account gravitational effects. The motion of a star relative to the Sun can provide useful information about the origin and age of a star, as well as the structure and evolution of the surrounding part of the Milky Way. In astronomy, it is widely accepted that most stars are born within molecular clouds known as stellar nurseries.

Cytoskeleton 2 Two families of motor proteins, called the kinesins and dyneins, that move along the microtubules, act like tow-trucks, attaching to the cargo and pulling it along the tracks to its destination. There are many kinds of kinesins and dyneins, each of which is believed to transport a different cargo.

Homemade Glue out of milk Casein (/ˈkeɪs.ɪn/ or /ˈkeɪˌsiːn/, from Latin caseus, cheese) is the name for a family of related phosphoproteins (αS1, αS2, β, κ). These proteins are commonly found in mammalian milk, making up 80% of the proteins in cow's milk and between 20% and 45% of the proteins in human milk. Casein has a wide variety of uses, from being a major component of cheese, to use as a food additive, to a binder for safety matches. As a food source, casein supplies amino acids, carbohydrates, and two essential elements, calcium and phosphorus.

It is a hairy biennial plant that can grow to 2 meters tall or more.erbascum thapsus is a dicotyledonous plant that produces a rosette of leaves in its first year of growth. The leaves are large, up to 50 cm long. The second year plants normally produce a single unbranched stem, usually 1–2 m tall.
