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.
DNA replication occurs during the S stage of interphase. Interphase is the stage between two mitotic or meiotic divisions. It can be slpit into three stages:G1, S and G2. During G1 (gap 1), cells grow and build up ATP on preparation for DNA replication. During the S (synthesis) phase the DNA is replicated. During the G2 phase the cell prepares itself for the process of cell division (mitosis or meiosis). See: http://www.emc.maricopa ....
