Cell biologists employ targeted fluorescent dyes or modified fluorescent prote9i

Question

Cell biologists employ targeted fluorescent dyes or modified fluorescent prote9ins in both standard deviation microscopy and confocal to deserve specific details in the cell. Even though fluorescence permits better visualization, power is microscope is limited by the _____ of light. absorption intensity filtering wavelength What is the smallest distance two points can be separated and still rested resolved using microscopy? 20 am 02 pm 2 pm 200 pm TRUE OR FALSE: Mamma Ian cells can be grown on a Petit dish. True False The pink color added to the DMEM media is an indicator of nutrients availability optimal temperature pH of the media Humidity level in the incubator Choose the best combination in the following statement: optimal conditions for growing mammalian cells are Incubators with 37 degree C 5% CO_2.10% O_2 37 degree C. 5% C0_2, humidity 30 degree C. 10% CO_2. humidity Room temperature, 5% Air, pH 7.4 We purchase immortalized mammalian cells for biomedical education and research from Wall Mart Hospitals CCTA ATCC

Explanation / Answer

12 Ans. Wavelength

The resolving power of a microscope is ultimately limited by the wavelength of light i.e. 400-600nm for visible light.
