Microbes are more susceptible to certain wavelengths of UV light, a function called the germicidal effectiveness curve. The curve for E. coli is given in the figure, with the most effective UV light having a wavelength of 265 nm. This applies to most bacteria and does not change significantly for other microbes.
The Inner Life of the Cell is an 8.5-minute 3D computer graphics animation illustrating the molecular mechanisms that occur when a white blood cell in the blood vessels of the human body is activated by inflammation (Leukocyte extravasation).
Psoralen crosslinks in virus DNA also appear to be removed by a recombinational repair process as occurs in SV40 virus infected cells, [23] and in herpes simplex virus infected cells. [24] One inaccurate process for repairing psoralen crosslinks appears to employ a DNA polymerase to fill in the gap formed in the strand with the two incisions ...

This is known as live-cell imaging. A few tools have been developed to identify and analyze single cells during live-cell imaging. [2] [3] [4] Time-lapse microscopy is the method that extends live-cell imaging from a single observation in time to the observation of cellular dynamics over long periods of time.
From January 2008 to December 2012, if you bought shares in companies when John V. Faraci joined the board, and sold them when he left, you would have a 7.0 percent return on your investment, compared to a -2.8 percent return from the S&P 500.
