When the rate of (*) individual events of this process occurring is constant, the molecular clock can be used to determine when two groups of life forms diverged.
A technique that analyzes the results of this process looks for a peak corresponding to a higher mass after using ethyl methanesulfonate in the first step. In some cases, after this process occurs, PCNA is ubiquitinated and an enzyme labeled with the letters eta or zeta is used in a process known as translesion synthesis. Artificially causing this process is done in TILLING and can be done in a site- directed manner. When the rate of (*) individual events of this process occurring is constant, the molecular clock can be used to determine when two groups of life forms diverged. Pyrimidine dimers are formed when this process occurs due to ultraviolet light exposure. Insertions or deletions can result in the "frameshift" type of this process, and the "point" type affects a single nucleotide. For 10 points, name this process, the alteration of the genome of an organism.
