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 is the duplication of two-strands of DNA. Transcription is the formation of single, identical RNA from the two-stranded DNA. Enzymes. The two strands are separated and then each strand's complementary DNA sequence is recreated by an enzyme called DNA polymerase.efinition. DNA replication is the replication of a strand of DNA into two daughter strands, each daughter strand contains half of the original DNA double helix. Uses the genes as templates to produce several functional forms of RNA. Products. One strand of DNA becomes 2 daughter strands.
