Actinic keratoses that develop on the lips are referred to as actinic cheilitis. The clinical appearance of an actinic keratosis is that of a small (several millimeters), red scaly papule or plaque, with induration and thickening of the epidermis.
1 Location: Ideally, the probe should be in close proximity to the forward or reverse primer, but should not overlap with a primer-binding site on the same strand. 2  Probes can be designed to bind to either strand of the target. 3  Melting temperature (Tm): Preferably, probes should have a Tm 6â8Â°C higher than the primers.
When a system is at equilibrium... When a system is at equilibrium, __________. a) the reverse process is spontaneous but the forward process is not. b) the forward and the reverse processes are both spontaneous. c) the process is not spontaneous in either direction.d) both forward and reverse processes have stopped.Follow.hen a system is at equilibrium...
