  1. Cloaca Cloaca
    Cloaca: A common passageway for feces, urine and reproduction. At one point in the development of the human embryo, there is a cloaca. It is the far end of a structure called the hindgut. This structure then divides to form a rectum, a bladder, and genitalia. The presence of a cloaca is normal in m...
  2. Cloacal exstrophy Cloacal exstrophy
    Cloacal exstrophy: A birth defect involving the pelvic area that is termed a malformation sequence and involves the cloaca. A cloaca is a common passageway for feces, urine and reproduction. During human embryogenesis (development), there is for a time a cloaca. The far end of a structure called th...
  3. Clone Clone
    Clone: Literally a fragment, the word in modern medical science has come to mean a replica, for example, of a group of bacteria or a macromolecule such as DNA. Clone also refers to an individual developed from a single somatic (non-germ) cell from a parent, representing an exact replica of that...
  4. Clone bank Clone bank
    Clone bank: Synonym for Genomic library. ...
  5. Clones, recombinant Clones, recombinant
    Clones, recombinant: Clones containing recombinant DNA molecules. ...
  6. Clonic seizure Clonic seizure
    Clonic seizure: A seizure in which there are generalized clonic contractions with the entire body jerking, but without a preceding tonic phase....
  7. Cloning Cloning
    Cloning: The process of making a clone, a genetically identical copy. Cloning can refer to the technique of producing a genetically identical copy of an organism by replacing the nucleus of an unfertilized ovum with the nucleus of a body cell from the organism. The first adult mammal cloned was Dol...
  8. Cloning vector Cloning vector
    Cloning vector: A DNA molecule originating from a virus, a plasmid (see below) or the cell of a higher organism into which another DNA fragment can be integrated without loss of the vector's (carrier's) capacity for self-replication. Cloning vectors are used to introduce foreign DNA into host cells,...
  9. Cloning, cell Cloning, cell
    Cloning, cell: The process of producing a group of cells (clones), all genetically identical, from a single ancestor. ...

  12. Clonote Clonote
    Clonote: The first cell produced by the combination of a nucleus and an enucleated ovum that launches the process of somatic-cell nuclear transfer (SCNT). As opposed to the zygote, the first cell resulting from fertilization. The term "clonote" was coined to connote the fundamental difference betwee...
  13. Clostridium Clostridium
    Clostridium: A group of anaerobic bacteria (bacteria that thrive in the absence of oxygen). There are 100+ species of Clostridium. They include, for examples, Clostridium difficile, Clostridium perfringens (also called Clostridium welchii), and Clostridium botulinum. Clostridium difficile is one of...
  14. Clostridium botulinum Clostridium botulinum
    Clostridium botulinum: A group of rod-shaped bacteria commonly found in the soil that grow best under low oxygen conditions. The bacteria form heat-resistant spores which allow them to survive in a dormant state until exposed to conditions that can support their growth. Clostridium botulinum produc...
  15. Clostridium difficile Clostridium difficile
    Clostridium difficile: A bacterium that is one of the most common causes of infection of the large bowel (colon). In technical terms, Clostridium difficile (C. difficile) is an obligate anaerobic or microaerophilic, gram-positive, spore-forming, rod-shaped bacillus. C. difficile is now recognized as...
