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.
Describe the process of DNA replication. One parental double-stranded DNA molecule is converted to two identical daughter molecules. The complementary structure of the nitrogenous base sewquences in the DNA molecule is the key to understanding DNA replication.
