addition unicellular organisms communicate with each other. Signals may use light‚ or touch but we will focus on chemical signals. 1. External signals are converted to responses within the cell a. Evolution of cell signaling i. In yeast a cells and αcells both secrete chemicals‚ which can only be received by the alternate type yeast. This signals the two cells to join via fusion 1. The process by which the signal on the surface of the cell is converted to a series of

discovered over twenty years ago. They exist as two noncovalently bound a- and b- subunits that function as adhesion molecules and play key roles in many biological processes including actin cytoskeleton organization and transduction of intracellular signals regulating cellular functions. Integrins bind a variety of extracellular matrices including collagens and laminins. The phenotypes observed from the generation of integrin knockout mice have provided a wealth of information on the unique biological

hook is used to represent a smoker’s addiction and the ‘Hidden smoke’ advert in which the cigarette smoke in the air is coloured black to see how much it effects those around you. This is also evident in the use of warnings on cigarette packaging. Health warnings have been printed on the front of cigarette packets since 1971‚ and there was a time when a simple ‘Smoking Kills’ would convince consumers to think twice about their need to smoke. However‚ as of October 2009‚ all cigarette packets in the

Introduction: Apart from being an essential component of bones‚ Calcium acts in many a different useful ways inside our bodies. And of all‚ the most important is its role in cell signaling. Calcium acts as a signal and most of the times as a second messenger‚ where it is released as a result of a signal and then triggers certain biological phenomenon within the cell. Calcium is stored in the Endoplasmic Reticulum and in the Mitochondria‚ and is also present outside the cell. A regular mechanism involving

Achondroplasia In humans achondroplasia is the most common form of non-lethal skeletal dysplasia (short limb dwarfism)‚ affecting over 250‚000 people worldwide. The incidence is approximately one in 10‚000-30‚000 live births. (1-7) Achondroplasia is characterised by short stature (average height of 120-132cm (2‚3)) with disproportionately shorter proximal limb bones‚ a long trunk with a narrow thorax‚ macrocephaly with frontal bossing and mid face hyperplasia. (1-4) People with achondroplasia also
