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.
Once the DNA in a cell is replicated, the cell can divide into two cells, each of which has an identical copy of the original DNA. DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules.Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.The replication process relies on the fact that each strand of DNA can serve as a template for duplication.eplication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.
