If you used gel electrophoresis to separate the same plasmid that has all three configuration of dna fragments, the supercoiled plasmid would move the fastest, while the multimer would move the slowest. why do the different plasmid configurations move the way they do through the gel?

What are some possible short and long term medical concerns for crew members on longer space exploration trips

The small molecule cyclic amp (camp) takes about 0.2 second to diffuse 10 μm, on average, in a cell. suppose that camp is produced near the plasma membrane on one end of the cell; how long will it take for this camp to diffuse through the cytosol and reach the opposite end of a very large cell, on average? assume that the cell is 200 μm in diameter.
