Colinearity
Colinearity: 1. In general, the arrangement of one sequence in the same linear order as another sequence.
2. In developmental genetics, the arrangement of genes on chromosomes in the same order as they are activated along the body axis during development, a principle discovered in 1957 by Edward Lewis.
3. In molecular genetics, the correspondence between the linear order of the nucleotide codons in the DNA, the sequence of messenger RNA, and the order of amino acids in the protein.

Messenger RNA: The key intermediary in gene expression, which translates the DNA’s genetic code into the amino acids that make up proteins. Abbreviated mRNA.
- Colitis
Inflammation of the large intestine (the colon). There are many forms of colitis, including ulcerative colitis, Crohn’s disease, infectious, pseudomembranous, and spastic. For example, intermittent rectal bleeding, crampy abdominal pain and diarrhea can be symptoms of ulcerative colitis. Diagnosis can be made by direct visualization using (sigmoidoscopy or colonoscopy) which is the most accurate test. […]
- Colitis, amebic
Colitis, amebic: Amebic dysentery (inflammation of the intestine) with ulcers in the colon due to infection with an ameba (Entamoeba histolytica), a single-celled parasite transmitted to humans via contaminated water and food. “Ameba” is from the Greek “amoibe” meaning “change” because amebae constantly change shape.
- Colitis, Crohn's
Colitis, Crohn’s: Crohn’s disease affecting only the large intestine (colon). Crohn’s disease is a chronic inflammatory disorder, primarily involving the small and large intestine, but which can affect other parts of the digestive system as well. It is named for the doctor who first described the disease in 1932. The disease is usually diagnosed in […]
