Clostridium difficile colitis or pseudomembranous colitis is colitis (inflammation of the large intestine) resulting from infection with Clostridium difficile, a spore-forming bacterium. It causes an infectious diarrhea called C. difficile associated diarrhea (CDAD).Latent symptoms of Clostridium difficile infection (CDI) often mimic some flu-like symptoms and may mimic disease flare-ups in people with inflammatory bowel disease âassociated colitis.C. difficile releases toxins that may cause bloating and diarrhea, with abdominal pain, which may become severe.atent symptoms of Clostridium difficile infection (CDI) often mimic some flu-like symptoms and may mimic disease flare-ups in people with inflammatory bowel disease âassociated colitis.

The initiation of DNA replication occurs in two steps. First, a so-called initiator protein unwinds a short stretch of the DNA double helix. Then, a protein known as helicase attaches to and breaks apart the hydrogen bonds between the bases on the DNA strands, thereby pulling apart the two strands.
replication. DNA replication is a crucial process; therefore, to ensure that mistakes, or mutations, are not introduced, the cell proofreads the newly synthesized 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.
