Culturing and visualizing cells Culturing and visualizing cells-test

1、问题: The most direct source of monoclonal antibodies are __ cells.
选项：
A:B lymphocytes
B:T lymphocytes
C:myeloma
D:Hybridoma
答案: 【Hybridoma】

2、问题:The fluorescent properties of dyes such as FITC can provide information on the
选项：
A:location of specific proteins.
B:concentration of ions in specific regions of the cell.
C:the amount of DNA in a cell.
D:volume of a cell.
答案: 【location of specific proteins.】

3、问题:What factors necessary for growth of animal cells in culture are provided by serum?
选项：
A:amino acids
B:precursors of DNA synthesis
C:growth factors
D:vitamins
答案: 【growth factors 】

4、问题:What is the advantage of using GFP-tag to visualize specific proteins, instead of staining cells with fluorescent dyes that bind to the target protein?
选项：
A:GFP fusions enable one to track changes in the location of the protein in living cells; staining usually requires fixed cells
B:GFP fusions enable higher resolution than staining with fluorescent probes.
C:GFP permits the position of the protein in the cell more precisely than fluorescent probes
D:GFP fusions are not subject to artifacts; fluorescent probes may introduce background artifacts.
答案: 【GFP fusions enable one to track changes in the location of the protein in living cells; staining usually requires fixed cells】
