Using the gas pedal analogy, the proto-oncogene would be an accelerator since they promote cell division and
deregulate apoptosis, while tumor suppressor would
be the brakes since they constrain the progress of the cell
cycle and induce cell apoptosis. An
oncogene is, therefore, when the accelerator
is stuck in down position and the brakes are not working.
Mitosis
Mitosis is the part of the cell cycle in which the duplicated genetic material (chromosomes) within the parent’s cell nucleus is separated to produce two daughter cells that are genetically identical to the parent. Mitosis is important to life because it is involved in the production of new cells for growth and to replace damaged cells. Mitosis occurs in five stages which are; interphase, prophase, metaphase, anaphase and telophase (cytokinesis).
Answer: Cellulose
Explanation:
Starch and cellulose are they two primary polysacharride found in plants.
Starch is the storage polysacharride found in plants in consisting of both linear chain amylose and branch chain amylopectin.
While Cellulose is the structural polysacharride in cell wall of plants. Cellulose consist of a linear chain of thousands of D-glucose units linked together by beta linkages.
