Top Cell Biology Interview Questions :: ALLInterview.com http://www.allinterview.com Top Cell Biology Interview Questions en-us What is lncap cell culture ? http://www.allinterview.com/showanswers/18573.html What are the Factors Affecting Transpiration ? http://www.allinterview.com/showanswers/21386.html These factors are as follows:- (1)Light:-During day time stomata remain open and so evaporation of water takes place normally; but at night these stomata are not open with the result transpiration is checked (2)Humidity of the Air:-When atmosphe Explain the Growth Harmones of plant? http://www.allinterview.com/showanswers/21413.html Growth of a plant has generally be believed due to the mineral and the food material but it is bow seen that growth of the plant is regulated by certain chemical substances which are synthesized by plants in very small quantities. These help in g How do I grow hybridoma cell lines as ascites, especially rat-mouse http://www.allinterview.com/showanswers/9316.html ATCC propagates most hybridomas as cell cultures in vitro, but many can be grown efficiently as ascites by inoculation into the peritoneal cavities of mice. Some rat-mouse hybridomas are more problematical as the host mouse strain may develop Explain about PHOTOSYNTHESIS ? http://www.allinterview.com/showanswers/21387.html Animals, non-green plants are directly or indirectly depended on the organic food prepared by green cells of plants. Green plants manufacture simple carbohydrates. E.g. sugars in the leaves by the chloroplast in the presence of sun what is the difference between flagella and cell walls? http://www.allinterview.com/showanswers/36281.html A flagellum (plural: flagella) is a long, slender projection from the cell body, composed of microtubules and surrounded by the plasma membrane. In small, single-cell organisms they may function to propel the cell by beating in a whip-like mo what is the difference between osmosis and diffusion rate? http://www.allinterview.com/showanswers/3520.html Osmosis rate is slow when compared to diffusion why because in osmosis molecules or ions moves from low concentration to high concentration .In diffusion ions moves from hihh to low concentration as this type of transport is passive transport Why do some cell lines require sodium pyruvate? http://www.allinterview.com/showanswers/9319.html Pyruvate is an intermediary organic acid metabolite in glycolysis and the first of the Embden Myerhoff pathway that can pass readily into or out of the cell. Thus, its addition to tissue culture medium provides both an energy source and a car What are the recommended carbon dioxide (CO2) levels needed to grow http://www.allinterview.com/showanswers/9317.html While the levels of carbon dioxide in cell culture systems vary from that in ambient air (about 0.03%) up to 40% in air, generally either no added CO2 or 5% to 10% CO2 in air are the most frequently used. Explain about Tissue ? http://www.allinterview.com/showanswers/21523.html Is a group of cells which are of same shape and formation. Cells of tissue have their common or origin Tissue can be classified into two groups. (1)Meristematic (2)Permanent (1)Meristenatic tissue:- Meristenatic tissue comprises those cells what is Cell Membrane Permeability? http://www.allinterview.com/showanswers/3245.html Cell membrane is the plasma membrane which is the selectively permeable membrane it allows only certain molecules to pass through it.It is otherwise called as differentially permeable membrane. what is confocal microscopy? http://www.allinterview.com/showanswers/18734.html Confocal microscopy is an imaging technique used to increase micrograph contrast and/or to reconstruct three-dimensional images by using a spatial pinhole to eliminate out-of-focus light or flare in specimens that are thicker than the focal plane How much can transient transfection expected from Lipofectamine 2000 http://www.allinterview.com/showanswers/3219.html How temperature affects Membrane Permeability? http://www.allinterview.com/showanswers/3225.html Membrane permeability is affected by temperature.when the temp is increasing upto certain level permeability of the cell increases by the loosening of cellular material. if the temperature incresed more and more the internal structure of the what is DNA? http://www.allinterview.com/showanswers/61895.html DNA is a deoxyribonucleic acid,a heriditery unit of any living being.DNA Mde up of a sugar ,a base and phophate.base i.e. 2 - purine & pyrimedine.
