Bai‚ W.-G. Zhu]; Department of Biotechnology‚ Guilin Medical College‚ Guilin‚ China [L. Bai] Since the p53 tumor suppressor gene has been found to be mutated in more than 50% of human cancers‚ it has attracted the interest of numerous researchers. The capacity of p53 for multiple biological functions can be

Chapter 2 Integrin Structure and Function Manakan Betsy Srichai and Roy Zent Abstract Integrins are a large family of heterodimeric glycoprotein receptors first 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

Plant Structure and Function Plant Body The unique organization of tissues in flowering plants is part of the reason why they are the dominant group of the plant kingdom. Monocots and Dicots Meristems Meristems – region of undifferentiated cells that can divide rapidly.

The structure and function of carbohydrates A carbohydrate is an organic molecule containing only Carbon‚ Hydrogen and Oxygen with the general formula Cn(H20)n. They are made up of individual molecules called monomers which are joined together by condensation reactions to make a longer chain called a polymer. Carbohydrates are categorised in to three main groups; monosaccharides‚ disaccharides and polysaccharides. Monosaccharides are single sugars and are sweet tasting soluble substances such

The nucleolus (plural nucleoli) is a non-membrane bound structure. Composed of proteins and nucleic acids found within the nucleus. Ribosomal RNA (rRNA) is transcribed and assembled within the nucleolus. Three major components of the nucleolus are recognized: the fibrillar centers (FC)‚ the dense fibrillar components (DFC)‚ and granular components (GC). The DFC consists of newly transcribed rRNA bound to ribosomal proteins‚ while the GC‚ contains rRNA bound to ribosomal proteins that are beginning
