Amino Acid Found in the Protein - Assignment Example In this pathway, regulation is majorly dependent on both positive and negative feedback mechanisms. Specifically, the positive feedback control mechanism is essential in the ripening of fruits and senescence of flowers. In tomato (Lycopersicon esculentum), there is an upsurge in ethylene production after exposure to exogenous ethylene. This, in turn, activates the activity of 1-Aminocyclopropane -1- Carboxylate Synthase. The role of 1-Aminocyclopropane-1-Carboxylate Synthase with regard to the ripening of fruits was first demonstrated in the year 1991. In this experiment, its role was fully understood in transgenic tomato plants that expressed the protein antisense Ribonucleic acid (RNA). Further experimental studies involving mutagenesis and crystallization of the enzyme, three-dimensional structures as well as amino acid residues have been of core importance in understanding its role. ACC synthase is beneficial in a number of ways including induction of apoptosis by oxidative stres s, response to both external stimulus and ethylene. ACC synthase is important in cellular response to iron ions. Additionally, the protein plays a vital role in response to wounding, mechanical stimulus as well as jasmonic acid. This protein is expressed during various developmental and growth stages such as anthesis, leaf senescence, bilateral and globular stage. Within the plant cell, at the molecular level, this enzyme is important in protein binding and is expressed in the flowers, leaf apex, embryo, stem and the leaves (Alexander and Don 2032).

Research Study - Assignment Example It was found that segmentation depends on a number of factors ranging from age, sexual orientation, education to even age. The benefits also spread far and wide from helping in identification of the most and least profitable customers, enabling grouping of consumers by factors like type and size of organization, category and lifestyle of consumers, geographical location, attitudes and behavior, enhancing customer service, helping a business build loyal relationships and so forth. Successful segmentation research, it was found, minimizes the number of segments only giving rise to a small number of big segments. Good research will enable classification of these groups through economic data and other essential information on how these segments change and develop over time. Both Bloomindale and Nordstrom offer high quality products and services though Nordstrom also serves customers of more modest means. Nordstrom Inc. is an upmarket American fashion department store, founded by Carl F. Wallin and John W. Nordstrom currently having its headquarters in Washington’s Seattle.
