Globular cluster

and dark matter. Galaxies range in size in lightyears. Galaxies, they are what holds our solar system and many, many more. We may not be alone because there is tons of galaxies out in this universe. Our galaxy, the milky way contains nebulas, clusters, black holes and maybe even other life. Our galaxy is what they call a spiral galaxy, there is a black hole that is pulling us around.…

Introduction Delphinus is a constellation that often passes by the watch of astronomers due to its limited size, however this little wonder has fascinating stars that captivate your attention when you take the time to focus upon it. Location South and away from the Milky Way's band lies the constellation Delphinus the Dolphin. This tiny grouping of stars lies in the transition zone from that of the summer star filled skies to that of the sparse autumn skies. Once you have located Delphinus…

All five of our different senses are important to have for a variety of reasons. They allow us to see, to feel, to hear, to smell, and to taste. There are also a lot of different parts of the body that allow us to experience these senses. If I had to choose which sense to lose though, I would choose to lose my sense of taste. One of our five senses is taste. The primary function of taste is to have us evaluate what we are eating. There are a few different areas that give us the ability to…

whereas Filopodia is the finger-like projection entirely comprised of actin. The movement of growth cone is regulated by polymerization/depolymerization of actin and tubulin. Polymerization is defined as the addition of strands in G-actin (monomeric Globular actin) to form F-actin (polymeric Fibrous actin). Various Rho family GTPases like RAC1 and CDC 42 activates ARP 2/3 and inhibits cofilin and promote polymerization of F-actin. Also, Rho A inhibits cofilin and promotes prolifin and…

Gene expression happens when cell’s DNA wraps around cluster of a globular histone proteins to form nucleosomes. Nucleosomes and histone are put together to make chromatin. When the structure of chromatin changes, it affects gene expression. This leads to epigenetics patterns of DNA methylation and histone modifications…

a rich supply of oxygen; its main responsibility is to deliver oxygen from the lungs to all of the body tissues and carbon dioxide from muscles to the lungs. Haemoglobin, with molecular mass of about 64500 kilodaltons, is a large conjugated and globular protein in red blood cells. Each molecule of haemoglobin is composed of four polypeptide chains, 2 alpha and 2 beta, each tightly associated with a prosthetic group (non-protein) of haem in its centre. Each central haem group…
