Hartwell‚ Tim Hunt and Sir Paul M. Nurse "for their discoveries of key regulators of the cell cycle". They have identified key molecules that regulate the cell cycle in all eukaryotic organisms‚ including yeasts‚ plants‚ animals and human. These fundamental discoveries have a great impact on all aspects of cell growth. Defects in cell cycle control may lead to the type of chromosome alterations seen in cancer cells. This may in the long-term open new possibilities for cancer treatment. 2. Read the

armed with cells that may function in defense and capture prey. The cells found within the tentacles are structurally and functionally unique to each phylum‚ such as the cindocytes in Cnidarians and colloblasts in Ctenophores. Cnidarians capture prey with special stinging cells called cindocytes. These cells are found throughout the epidermis but are particularly abundant in the tentacles. Cnidocytes contain a cilium or modified cilium structure with a kinetosome at its base. This structure is known

Coordination is the process through which two or more organs interact and complement the functions of one another. For example‚ when we do physical exercises‚ the energy demand is increased for maintaining an increased muscular activity. The supply

EXPERIMENT 1: REACTIONS OF ENOLATE IONS WITH CARBONYL GROUPS Aims In this experiment we used two techniques for the reactions of enolate ions with carbonyl groups. One technique used was Doebner reaction and the other technique used was Claisen-Schmidt reaction. Therefore the aim of this experiment is to synthesize trans p-methoxycinnamic acid and to synthesize dibenzalacetone via an aldol condensation reaction between acetone and benzaldehyde. The products would be recrystallized using ethanol

Biology Notes 1.02 Sometimes a practice or belief claims to be science but does not follow the scientific method or cannot be proven reliable through experimentation. These practices are examples of pseudoscience‚ which literally means "fake science."
