Incontinence-associated dermatitis (IAD) is predominantly a chemical irritation resulting from urine or stool coming in contact with the skin. Ammonia from urine and enzymes from stool can disrupt the acid mantle of the skin and eventually cause the skin to break down. As with the other forms of MASD discussed above, maceration also plays a key role in the formation of IAD, and can makes the skin more susceptible to friction damage.
DNA Replication. DNA replication is a process wherein copies of DNA molecules are produced within the cell nucleus. This replication process is vital because it facilitates the transfer of genetic information from one generation to another.he DNA replication process is a procedure wherein the DNA double helix splits and duplicates itself to make copies of the strands of DNA.
Replication occurs during interphase. Interphase is the stage of the cell cycle in which cells spend most (typically, more than 90%) of their time and perform their customary functions, including preparation for cell division. When this phase begins, the chromosomes have not yet replicated, but by the beginning of prophase replication is complete, so that each chromosome is composed of two sister chromatids.
