WebbONCOGENES AND TUMOR SUPPRESSOR GENES. Oncogenes arise as the result of mutations in normal genes (called proto-oncogenes) that regulate processes such as cell cycle progression. 5 As a result of these mutations, the protein products normally encoded by these genes are altered in a way that results in new or increased activity within the … Webb29 feb. 2016 · With protocells, scientists probe the chemistry that started biology Researchers design cell-like compartments to figure out how Earth’s first cells might …

While modern cells can rely on complicated protein machineries to catalyze these crucial processes, protocells must have accomplished this using more simple mechanisms. Protocells composed of fatty acids [54] would have been able to easily exchange small molecules and ions with their environment. [1] Visa mer A protocell (or protobiont) is a self-organized, endogenously ordered, spherical collection of lipids proposed as a stepping-stone toward the origin of life. A central question in evolution is how simple protocells first arose … Visa mer Self-assembled vesicles are essential components of primitive cells. The second law of thermodynamics requires that the universe move in a direction in which disorder (or entropy) increases, yet life is distinguished by its great degree of organization. … Visa mer Langmuir–Blodgett deposition Starting with a technique commonly used to deposit molecules on a solid surface, Langmuir–Blodgett … Visa mer Compartmentalization was important in the origins of life. Membranes form enclosed compartments that are separate from the external environment, thus providing the cell … Visa mer When phospholipids are placed in water, the molecules spontaneously arrange such that the tails are shielded from the water, resulting in the formation of membrane … Visa mer Eigen et al. and Woese proposed that the genomes of early protocells were composed of single-stranded RNA, and that individual genes … Visa mer Protocell research has created controversy and opposing opinions, including criticism of vague definitions of "artificial life".
